FREXP(3)	       FreeBSD 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'').
