FREXP(3)		 BSD 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 num‐
     ber 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”).
