# Floating-point meaning

Of, relating to, or being a method of writing numeric quantities with a mantissa representing the value of the digits and a characteristic indicating the power of the number base, such as 3 × 10

^{−5}.adjective

Designating or of a system of arithmetic, used esp. in computer science, having its numbers expressed in scientific notation (Ex.: 0.0003 becomes 3 × 10

^{-4})adjective

Relating to a method of representing numerical quantities that uses two sets of integers, a mantissa and a characteristic, in which the value of the number is understood to be equal to the mantissa multiplied by a base (often 10) raised to the power of the characteristic. Scientific notation is one means of displaying floating-point numbers.

A method for storing and calculating numbers in which the decimal points do not line up as in fixed point numbers. The significant digits are stored as a unit called the "mantissa," and the location of the radix point (decimal point in base 10) is stored in a separate unit called the "exponent." Floating point methods are used for calculating a large range of numbers quickly.Floating point operations can be implemented in software or in a floating point unit (FPU), which may be a separate "math coprocessor" chip or a circuit in the CPU. See math coprocessor, binary numbers and NaN.
