# U+FF10Fullwidth Digit Zero

U+FF10 was added in Unicode version 1.1 in 1993. It belongs to the block U+FF00 to U+FFEF Halfwidth and Fullwidth Forms in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Decimal Number and is commonly used, that is, in no specific script. The codepoint has the decimal value 0.

The glyph is a wide version of the glyph Digit Zero. Accordingly, its width in East Asian Text is fullwidth. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. This number joins with other adjacent letters and numbers to form a word. U+FF10 offers a line break opportunity at its position, except in some numeric contexts.

0 (zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. In mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 has the result 0, and consequently, division by zero has no meaning in arithmetic.

As a numerical digit, 0 plays a crucial role in decimal notation: it indicates that the power of ten corresponding to the place containing a 0 does not contribute to the total. For example, "205" in decimal means two hundreds, no tens, and five ones. The same principle applies in place-value notations that uses a base other than ten, such as binary and hexadecimal. The modern use of 0 in this manner derives from Indian mathematics that was transmitted to Europe via medieval Islamic mathematicians and popularized by Fibonacci. It was independently used by the Maya.

Common names for the number 0 in English include zero, nought, naught (), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (). Informal or slang terms for 0 include zilch and zip. Historically, ought, aught (), and cipher have also been used.
