    Printing out only the decimal places for a number in C?

    Hello, I am trying to create a program that will read a double precision floating point number and output only the decimal part of the number given. For example, Input: 2.39 Output: 0.39
    I am struggling to overcome this hurdle. So far I can only make it output 0.00.

    Code:
    int main (void){
        double amount = 0.0;
        int Loonies = 0;
    
    
        printf("Please enter the amount to be paid: $"); 
        scanf("%if",&amount);
        
        printf("Loonies required: %i", amount);
        printf(", balance owing $%0.2f", amount);
    
    
            return 0;
    }
    Any help or suggestions would be greatly appreciated!

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
