You can't use the == operator on floating point variables.

Values that are close will test as equal due to rounding.

You need to compare the values as one less than the other within an allowed margin of error.

What are you trying to accomplish?

Is this perchance a homework assignment that seeks to test your ability to understand this code? I suggest your review the required behavior of the C compiler when an operator (in this case '==') has operands of different types (in this case int and float).
