    Ok that is a different question than what you had posted before.
    To check if a number has a decimal am I tired...
    I think you will use the '%' symbol. I will get back with you on that.....right now it is bed time, and I can not think.

    Ok, you can easily test if a floating point variable has desimal numbers.
    if (Variable == (int)Variable)  // test if there is no desimals
    if ( !(Variable == (int)Variable) )  // test if there are desimals
    This tests if the floating point value is same as its integer conversion.
    Making error is human, but for messing things thoroughly it takes a computer

    Read the input as a string, then use (say strchr) to look for a decimal point.

    Do what you need to do, depending on whether you find one or not.
