C / C ++modf() in

The functionmodf()used to split the passed parameter into integer and decimal. Declare the variable in the 'math.h' header file for mathematical calculations. It returns the fractional value of the passed parameter.

This ismodf()C Language Syntax

double modf(double value, double　*integral_pointer);

Here,

Value-value divided into integer and fraction.

Integral Pointer-points to the integer part after the split.

This ismodf()C Language Example

Example

#include<stdio.h>
#include<math.h>
int main () {
　　　double val, x, res;
　　　val =　28.856;
　　　res = modf(val, &x);
　　　printf("Integral part of val: %lf\n", x);
　　　printf("Fraction Part of val: %lf \n", res);
　　　return(0);
}

Output Result

Integral part of val:　28.000000
Fraction Part of val: 0.856000

In the above program, the functionmodf()Divides a floating-point number into its integer and fractional parts. Declare three variables as val, x, and res. The variable res stores the value calculated by the computationmodf().

res = modf(val, &x);
