One half is the rational number that lies midway between 0 and 1 on the number line. Multiplication by one half is equivalent to division by two, or "halving"; conversely, division by one half is equivalent to multiplication by two, or "doubling". A square of side length one, here dissected into rectangles whose areas are successive powers of ...
The set of all half-integers is often denoted + = . The integers and half-integers together form a group under the addition operation, which may be denoted [2] . However, these numbers do not form a ring because the product of two half-integers is not a half-integer; e.g. = . [3] The smallest ring containing them is [], the ring of dyadic rationals.
Rounding a number x to the nearest integer requires some tie-breaking rule for those cases when x is exactly half-way between two integers – that is, when the fraction part of x is exactly 0.5.
English number words include numerals and various words derived from them, ... Thus one-half would be written 0.5 in decimal, base ten notation, and fifty thousand as ...

And because a negative divided by a negative produces a positive, −1 / −2 represents positive one-half. In mathematics a rational number is a number that can be represented by a fraction of the form a / b , where a and b are integers and b is not zero; the set of all rational numbers is commonly represented by the symbol Q or ...
