FREXP(3)		  OpenBSD Programmer's Manual		      FREXP(3)

NAME
     frexp, frexpf, frexpl - convert floating-point number to fractional and
     integral components

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() function breaks a floating-point number into a normalized
     fraction and an integral power of 2.  It stores the integer in the int
     object pointed to by exp.	The frexpf() function is a single precision
     version of frexp().  The frexpl() function is an extended precision
     version of frexp().

RETURN VALUES
     The frexp(), frexpf() and frexpl() functions return the value x, such
     that x is a double with magnitude 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() function conforms to ANSI X3.159-1989 (``ANSI C'').
