Information About0 (number) |

0 ('''zero''') is both a Number and a Numeral . Zero is the last numeral to be created in most numerical systems, and has sometimes been represented only by a gap. In the English language, zero may also be called '''nil''' when a number, '''o'''/'''oh''' when a numeral, and '''nought'''/'''naught''' in either context. 0 AS A NUMBER 0 is the Integer that precedes the positive 1 , and follows −1 . Zero first appeared as a number in Brahmagupta 's work dated to 628 . Prior to that Babylonians used a space marker that played one of the functions of zero. Babylonians did not have a special symbol for zero. In most (if not all) numerical systems, 0 was identified before the idea of 'negative integers' was accepted. Zero is an integer which quantifies a count or an amount of Null size; that is, if the number of your brothers is zero, that means the same thing as having no brothers, and if something has a weight of zero, it has no weight. If the difference between the number of pieces in two piles is zero, it means the two piles have an equal number of pieces. Before counting starts, the result can be assumed to be zero; that is the number of items counted before you count the first item and counting the first item brings the result to one. And if there are no items to be counted, zero is remains the final result. While mathematicians all accept zero as a number, some others would say that zero is not a number, arguing one cannot have zero of something. Others hold that if you have zero dollars in your bank account, you have a specific quantity of money in your account, namely none. It is that latter view which is accepted by mathematicians and most others. Almost all Historian s omit the Year Zero from the Proleptic Gregorian and Julian Calendar s, but Astronomer s include it in these same calendars. However, the phrase Year Zero may be used to describe any event considered so significant that it virtually starts a new time reckoning. 0 AS A NUMERAL The modern numeral 0 is normally written as a circle or (rounded) rectangle. On the Seven-segment Display s of calculators, watches, etc., 0 is usually written with six line segments, though on some historical calculator models it was written with four line segments. This variant glyph has not caught on. Early Europeans hesitated to consider zero as a numeral or number. Leonardo of Pisa or Fibonacci says the following in 1202 AD when the Indian number system arrived in Europe.
