This is my code:

This is my first value. That is 8.

This is my next value. That is 11.

This is my integer value. That is 107.

My expect return value is 271.78 but it return back me 271.78(0)3. That make me wonder why? I tried to casting foot and inch to double but it not work.

Is floating point math broken? show me how to compare but i need to return a right number. It can't help me.
