NAME
     frexp -- 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);

DESCRIPTION
     The frexp() function breaks a floating-point number into a normalized fraction and an inte-
     gral power of 2.  It stores the integer in the int object pointed to by exp.

RETURN VALUES
     The frexp() function returns 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 C89'').
