mathematics, a negative number is the opposite of a positive real number. Equivalently, a negative number is a real number that is less than zero. Negative numbers...

In mathematics, the sign of a real number is its property of being either positive, negative, or 0. Depending on local conventions, zero may be considered...

the first to present a calculation involving the square root of a negative number, it was Rafael Bombelli who first set down the rules for multiplication...

of the extended real number line such that +1⁄−0 = −∞ and +1⁄+0 = +∞; division is undefined only for +±0⁄±0 and +±∞⁄±∞. Negatively signed zero echoes the...

In mathematics, −1 (negative one or minus one) is the additive inverse of 1, that is, the number that when added to 1 gives the additive identity element...

numbers, the square root of a negative number is undefined, as no real number exists which, when squared, equals a negative number. Mathematicians, including...

defined as a number and may therefore be represented by NaN in computing systems. The square root of a negative number is not a real number, and is therefore...

positive and negative integers in a way that they can use the same algorithm (or mechanism) for addition throughout the whole range. For a given number of places...

changing the represented number; for example, 15 = 15.0 = 15.00 and 5.2 = 5.20 = 5.200. For representing a negative number, a minus sign is placed before...

positive or negative number when divided by zero is a fraction with the zero as denominator. Zero divided by a negative or positive number is either zero...

of a negative number—al-nāqiṣ—by a positive number—al-zāʾid—is negative, and by a negative number is positive. If we subtract a negative number from a...

always, if the sign bit is 0, the number is non-negative (positive or zero). If the sign bit is 1 then the number is negative. Formats other than two's complement...
