    Seperating Main And Fractional Numbers

    How do you get one FLOAT variable to seperate into a main number and fraction.

    i.e. If I had a FLOAT variable of 1.234, how do I get 1.234 into 2 new variables of 1.000 and 0.234.

    I hope you understand the question!.

    It's called modf(), and it's found in math.h

    Reading the manual page for it is up to you.
    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.

    assign the float to an integer for the integer value.
    subtract that integer value from the original float to get the fractional part.
