Haskus.Format.Binary.FixedPoint
Description
Fixed-point numbers
Synopsis
- data FixedPoint w (i :: Nat) (f :: Nat)
- toFixedPoint :: forall a w (n :: Nat) (d :: Nat). (RealFrac a, BitSize w ~ (n + d), KnownNat n, KnownNat d, Bits w, Field w, Num w, Integral w) => a -> FixedPoint w n d
- fromFixedPoint :: forall a w (n :: Nat) (d :: Nat). (RealFrac a, BitSize w ~ (n + d), KnownNat n, KnownNat d, Bits w, Field w, Num w, Integral w) => FixedPoint w n d -> a
Documentation
data FixedPoint w (i :: Nat) (f :: Nat) Source #
Fixed-point number
* w is the backing type
* i is the number of bits for the integer part (before the radix point)
* f is the number of bits for the fractional part (after the radix point)
