Problem
1. Given two Float parameters called High and Low, write the specification for a function called Epsilon that returns a Float result.
2. Given three Float parameters called Num_1, Num_2, and Difference, write the specification for a function called Equal that returns a Boolean result.
3. Write the body for the function you specified in the previous question. True should be returned if the absolute difference between Num_1 and Num_2 is less than the value in Difference. Otherwise return False.
