Init with hsv formant bug

[bulat-f]

For example:

"hsv(100, 75%, 50%)".paint.to_hex # got: "#408020" expected: "#3F7F1F"

In fact #3F7F1F is hsv(100, 75%, 50.2%). Rounding error.

Hi @fatbulat. Life has been very busy for me the past several months, so I've unfortunately had to neglect this repo for a bit :/

Can you confirm where you're getting #3F7F1F from? I've tried three different online HSV converters (like http://colorizer.org/) and they all give me #408020 like Chroma. If you do find an input producing bad output, please let me know. My math could be off in the code, but in this case it looks correct.
