Math.frexp
From GiderosMobile
Available since: Gideros 2011.6
Class: math
Description
Used to split a floating-point number (v) into a normalized fraction (a mantissa) and an integer exponent.
(number) (number) = math.frexp(v)
Returns m and e such that v = m*2^e, e is an integer and the absolute value of m is in the range [0.5, 1) (or zero when v is zero).
Parameters
v: (number) value
Return values
Returns (number) the mantissa, a multiplier in the range [0.5, 1) (normalized fraction)
Returns (number) the exponent as an integer
Note
math.ldexp is the inverse operation.
