    a function to return fraction

    Hello,

    I need a function which returns the fraction part of a number.
    I mean if the input to the function is 5.678, I need the output to be 0.678.

    Is there a built in function to do so in C++?

    Thank you
    arian

    You could #include <cmath> and use std::fmod.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
