NAME frexp - split float into fraction and exponent SYNOPSIS mixed *frexp(float x) DESCRIPTION The argument is split into a fraction f and an integer exponent n, such that either f == 0.0, or 0.5 <= | f | < 1.0, and f * 2 ** n == x. ({ f, n }) is returned. If x == 0.0, both f and n will be zero. SEE ALSO kfun/ldexp, kfun/modf
