Counting the number of decimal places in pascal

Question

I just started studying pascal and I have to do a pascal program as homework. I made it but I don\'t know how to count the number of decimal places in a real number<

Answer 1

if you're actually doing a writeln() output, surely just writeln(x); would accomplish what you're after? If you actually want to count the number of decimals, you'd probably have to convert to a string, remove any trailing zeroes, and see where the decimal point landed.
