FREXP(3) Library Functions Manual FREXP(3) NAME frexp, frexpf, frexpl -- convert floating-point number to fractional and integral components LIBRARY Math Library (libm, -lm) SYNOPSIS #include <math.h> double frexp(double value, int *exp); float frexpf(float value, int *exp); long double frexpl(long double value, int *exp); DESCRIPTION The frexp(), frexpf() and frexpl() functions break a floating-point number into a normalized fraction and an integral power of 2. They store the integer in the int object pointed to by exp. RETURN VALUES These functions return the value x, such that x is a double with magni- tude in the interval [1/2, 1) or zero, and value equals x times 2 raised to the power *exp. If value is zero, both parts of the result are zero. SEE ALSO ldexp(3), math(3), modf(3) STANDARDS The frexp(), frexpf(), and frexpl() functions conform to ISO/IEC 9899:1999 ("ISO C99").
