Example of the early Greek symbol for zero (lower right corner) from a 2nd century papyrus

In mathematics <math>-0 = 0 = +0</math>, both −0 and +0 represent exactly the same number, i.e., there is no "negative zero" distinct from zero. In some signed number representations (but not the two's complement representation used to represent integers in most computers today) and most floating point number representations, zero has two distinct representations, one grouping it with the positive numbers and one with the negatives; this latter representation is known as negative zero.
