Numeric.Half

Description

Half-precision floating-point values. These arise commonly in GPU work and it is useful to be able to compute them and compute with them on the CPU as well.

Synopsis

newtype Half = Half {
- getHalf :: CUShort
}
isZero :: Half -> Bool
fromHalf :: Half -> Float
toHalf :: Float -> Half
pattern POS_INF :: Half
pattern NEG_INF :: Half
pattern QNaN :: Half
pattern SNaN :: Half
pattern HALF_MIN :: Half
pattern HALF_NRM_MIN :: Half
pattern HALF_MAX :: Half
pattern HALF_EPSILON :: Half
pattern HALF_DIG :: (Eq a, Num a) => a
pattern HALF_MIN_10_EXP :: (Eq a, Num a) => a
pattern HALF_MAX_10_EXP :: (Eq a, Num a) => a
