And once Zero was used, then followed negatives, etc. 18 April, 2016. Counting was invented long before zero was. programming languages, an index begins at zero for an array, string, etc. Nobody who has had any contact with assembler would ask this question:). Zero as a placeholder was invented independently in civilizations around the world, said Dr. Annette van der Hoek, Indiologist and research coordinator at the Zero Project. It's still important to understand how this addressing works especially when working with lower-level languages. Once all sheep have passed, discard of excess stones. ... so they invented different clay tokens to represent different numbers of each specific commodity, and by 4000 BC strung the tokens like beads on a string. History has it that zero was invented independently by three civilisations, the Babylonians, the Mayans and the Indians. Paul Ratner. They did this because the 1130 indexed addressing allowed signed offsets, requiring offsets to start at zero would have thrown away half of the possible size of the table, and that table NEEDED to be big.). The first element is at the starting point, so you multiply the size of the element by zero to get zero which is what you add to the starting address to find the location of the first element. I believe it was the Chinese who "came up with" zero. Feasibility of a goat tower in the middle ages? What caused this mysterious stellar occultation on July 10, 2017 from something ~100 km away from 486958 Arrokoth?

Log in or Sign up log in sign up. Wiki User Answered . Mathematics (from Greek: μάθημα, máthēma, 'knowledge, study, learning') includes the study of such topics as quantity (number theory), structure (), space (), and change (mathematical analysis). FORTRAN, which predates almost everything else out there, started at 1, because engineers, mathematicians, and scientists have been counting starting at 1 for millenia. Think of it as an offset from the beginning. Since the zero and positional notation were invented, everyone counts 10s, 100s, 1000s etc. Why do most language's definition of substring allow substring(“abc”, 3) => “”. Why was the percent sign (%) chosen as the format specifier for the printf family of functions? Differences in meaning: "earlier in July" and "in early July", Grammatical structure of "Obsidibus imperatis centum hos Haeduis custodiendos tradit". Then in 1890 Japanese mathematicians worked on it and created ‘integers’. Words which meant ‘void,’ ‘sky,’ ‘space’ all represented nothingness or zero. At the time that C was developed, 1-based counting was the norm, but requiring the compiler to keep track of that silly extra 1 was considered to be too much work for the compiler. Cookies help us deliver our Services. What is the origin of counting from zero in programming languages? I think both WBT and btilly offer equally good reasons; I wondered if anyone who perhaps knew old (pre-C?) What is the origin/meaning of the name 'NHibernate'? u/gratedcheeseinoven. Zero was spread by Arabians to Europe and there on it was spread all over to Asia and China and Russia, Australia, Canada, Florida, Boston and everywhere to include the coldest city on Earth. How much did the first hard drives for PCs cost? Zero is an acceptable end-of-file return because it never is a valid line length." The base-2 numeral system is a positional notation with a radix of 2. This causes some frustrations for the (relatively small subset of?) You have an address, which points to the location in memory where the array begins. When the zero was not invented, how the people were counting ? So, for instance in K&R's C, when discussing array indexes, K or R matter-of-factly explains, "Array subscripts always start at zero in C..." (p. 22) Later, in discussing a function to process character arrays, "... a more useful design would be to return the length of the line, or zero if end of file is encountered. share. all?) To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Can you specify what exactly it is you want to know? I thought, perhaps, it had to do with all being rooted in binary. (p. 127). First, the great Arabian voyagers would bring the texts of Brahmagupta and his colleagues back from India along with spices and other exotic items. programmers who frequently switch between programming languages that start counting at different values. Assembly languages typically started from 0 because arrays are traditionally defined in terms of a starting address and an offset from the starting address. Now each morning and evening thereafter, pass the sheep by you removing the stones from your pile. Here are a couple possibilities: 1. Press question mark to learn the rest of the keyboard shortcuts. I know K&R is so widely regarded for its clear prose, so that's another reason I include it, to give an example of what I had hoped another documented language would do to explain the reason behind zero-indexing. I don‘t understand the question. In practical arithmetic the merchants have been far ahead of the scribes, for the idea of zero is in use in the market place long before its adoption in written systems. What are programming languages written in? - 8415047 The IBM 1130 Executive had a large resident vector table, whose "starting address" was actually in the middle of the table. An exception: MATLAB and some other languages bucked the trend and went with an index starting at 1, apparently under the impression that it would be a first programming language for a lot of their target users and that for those folks, starting with 1 makes more intuitive sense. A latin word meaning “untouched”. How do I disable 'Warning: Unsafe Paste' pop-up? Then to access any element, you multiply the array index by the size of the element and add it to the starting address, to find the address for that element. Early history: Angled wedges. I recognize it became convention over time, adopted in many languages, but can anyone point to the origin of this? And at the same time I recognize such information may not exist. I told you above that Animals and Birds also can count. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service.

Here is an excerpt from wikipedia: The concept of zero as a digit in the decimal place value notation was developed in India, presumably as early as during the Gupta period (c. 5th century), with the oldest unambiguous evidence dating to the 7th century. save hide report. How did people count before numbers were invented? Numbers Around the World . Move each sheep by you one-by-one into an enclosed area. A similar type of symbol cropped up independently in the Americas sometime around 350 A.D., when the Mayans began using a zero marker in their calendars. The story begins some 5,000 years ago with the Sumerians, those lively people who settled in Mesopotamia (part of what is now Iraq). Then he thought of inventing a number system of adding and multiplication. In this system, the year 1 BC is followed by AD 1. Can I walk along the ocean from Cannon Beach, Oregon, to Hug Point or Adair Point? They widely used it in calculations, astronomy and astrology. New comments cannot be posted and votes cannot be cast, More posts from the NoStupidQuestions community, Press J to jump to the feed. For numbers themselves they just used a numbering system which didn't use a symbol for zero. In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" and "1" ().. The number zero was invented in the last 1,000 years to form a transition between positive and negative numbers. Zero was invented in India by Indian mathematicians dating as early as 5th century. 3 tens is 2⑩ (20 + 10). (This allows a very concise, very nice algorithm for the 8-queens problem.) Top Answer. The innovative Italians of the Renaissance (14th through 16th century) are widely acknowledged to be the fathers of modern accounting. How did people count before numbers were invented?

There was never a need to count zero things. Answer. Without zero you can't use a positional system like we do, so you need a symbol for 10, a different one for 10,000 etc, or something complex like that. I'm not necessarily looking for the why (which I very much appreciate because it helps further an understanding) but more along the lines of when did this become the convention and/or whether it can be traced to a specific language. Counting is much older than the zero. If your number system doesn't assign meaning to the placement of a digit then you can get by without a zero.

Counting from zero is popular not just in programming languages but in mathematics more generally speaking. Which they had. Should my sequential collection start at index 0 or index 1? I believe COBOL started at 1, but I do not recall for certain, and I have no intention of refreshing some very painful memories, because accountants, like engineers, scientists, and mathematicians, start counting at 1. Asked by Wiki User. What did you come up with? Then myarray[0] and myarray+0 is the same element, and myarray[1] and myarray+1, etc. MATLAB copied FORTRAN, as it was aimed at almost precisely the same user community. Efficient way of evaluating an array of strings then add to an array in Ruby. in China and was used in many ancient civilizations, including Persia and Egypt. As a number zero is a theoretical plaeholder that has no real meaning other than enabling calculations. Basically the same, you don't really need zero for counting. There's something more complicated going on than "zero enables positional numbers". So like I said, you don't technically need a symbol for zero, just for 10. Zero reached Baghdad by 773 AD and would be developed in the Middle East by Arabian mathematicians who would base their numbers on the Indian system. The convention spread because programmers started working in very low-level languages where memory addresses were directly manipulated and in most cases building up from there, maintaining the same convention at each step so that they wouldn't have to relearn or be prone to mistakes when switching between conventions. The earliest use of zero in the calculation of the Julian Easter occurred before AD 311, at the first entry in a table of epacts as preserved in an Ethiopic document for the years AD 311 to 369, using a Ge'ez word for "none" (English translation is "0" elsewhere) alongside Ge'ez numerals (based on Greek numerals), which was translated from an equivalent table published by the Church of Alexandria in Medieval Greek. The Wikipedia article on this topic also cites a common machine instruction used when working "backwards" and detecting the end of a loop, namely "decrement and jump if zero.". It is my distant recollection that PL/I allowed you to start and stop wherever you liked. 2016-04-11 14:43:19 2016-04-11 14:43:19. How did they count before 0 was invented? Ada followed PASCAL.

We tend to think of zero as "absence" when in fact it does not represent anything in the real world at all. @user6292850 I agree it's a useful reference, but I don't think it's a dupe. Based on K&R, I gather a) the convention is adopted from elsewhere, so C is not the inspiration behind zero-indexing and b) there are possibly deeper reasons for its use based on the second example. What is a "constant time" work around when dealing with the point at infinity for prime curves? (Mentioning Ada should be good for at least three downvotes right there.). But I am not sure of the idea carrying to the necessity in the decimal system -- why not start an index from 1? The Indian scholar Pingala used binary numbers and was the first to use the Sanskrit word ‘sunya’ for zero. Full Disclosure: I've never done PL/I coding, just skimmed a book, and I have no intention of changing that. At one time, human beings who are also animal were able to count only upto 9.

But it would still be a few centuries before zero reached Europe. They just wrote something equivalent to "nil" or "nothing" to indicate zero items. Since the zero and positional notation were invented, everyone counts 10s, 100s, 1000s etc. There was a token for one sheep, a different token for ten sheep, a different token for ten goats, etc. PASCAL actually requires the programmer to say where he starts and finishes, allowing one to define, for example, and array whose indices run from, say, -7 to +7. But, only to certain limits. What are your thoughts? It put a fair burden of the workload on the programmer, where other languages had the compiler and the machine do the heavy lifting.
