1`7.813094473379822E-4` does not equal `7`, so why would you want to make it `7`? Converting this value to an integer would result in `0`. – Bryan Nov 23 '16 at 14:55

@saipavan: no not "round it to 8". You don't seem to understand that `7.81...E-4` is another way to write `0.000781...`. Rounding that to an integer results in `0`, not `7` or `8`. – Rudy Velthuis Nov 25 '16 at 15:59
