How to extract the decimal part from a floating point number in C?

Question

How can we extract the decimal part of a floating point number and store the decimal part and the integer part into two separate integer variables?

Answer 1

Suppose A is your integer then (int)A, means casting the number to an integer and will be the integer part, the other is (A - (int)A)*10^n, here n is the number of decimals to keep.
