    Question regarding extraction of value from a decimal fraction

    Dear All,


    I want to extract the integer value just after the decimal point from any number, for example integer 1 from 1.250. Below is my code for the same. However, I get an error while extracting the integer value(written below the code):

    Code:
    #include<stdio.h>
    #include<stdlib.h>
    int main()
    {
        float i=1.25,num=0;
        num=i%10;
        printf("%f",num);
        system("pause");
        return 0;
    }
    "invalid operands to binary % "

    Please suggest modifications/changes. Thank you.

    #include <math.h> and use fmod.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
