MODF
Synopsis
#include <math.h>
double modf (double value, double * iptr)
Description
The modf() function splits the argument value into integral and fractional parts, each having the
same sign as value. For example, -3.17 would be split into the integral part (-3) and the fractional
part (-0.17).
The integral part is stored as a double in the object pointed to by iptr.
Example
#include <math.h>
#include <stdio.h>
void
main (void)
{
double i_val, f_val;
f_val = modf( -3.17, &i_val);
}
Return Value
The signed fractional part of value.
