fi :: (Integral a, Num b) => a -> bSource
Short-hand for fromIntegral
hsv2rgb :: Fractional a => (Integer, a, a) -> (a, a, a)Source
Conversion scheme as in http:en.wikipedia.orgwikiHSV_color_space
mapAccumLM :: Monad m => (acc -> x -> m (acc, y)) -> acc -> [x] -> m (acc, [y])Source
The mapAccumLM
function behaves like a combination of mapM
and
foldlM
; it applies a monadic function to each element of a list,
passing an accumulating parameter from left to right, and returning
a final value of this accumulator together with the new list.
