Syntax
#include <math.h>
double frexp(value, exp)
double value; /* input floating-point number */
int *exp; /* pointer to exponent */
Defined in frexp.obj in rts.lib
frexp
Description The frexp function breaks a floating-point number into a normalized fraction
and an integer power of 2. The function returns a value with a magnitude
in the range [~,1} or 0, so that value = x x 2(**exp). The frexp function
stores the power in the int pointed to by expo If value is 0, both parts of
the result are 0.
Example double fraction;
int exp;
fraction = frexp(3.0, &exp);
/* after execution, fraction is .75 and exp is 2 */
