Data.ByteString.Read.Class

Documentation

class (Fractional a, Num (Fraction a), Ord (Fraction a)) => ReadFractional a where Source

Associated Types

data Fraction a Source

data type to store fractional part of floating

Methods

maxValue :: proxy a -> Maybe (Fraction a) Source

maximum value of fractional part.

Nothing if arbitrary-precision.

Just $ fromIntegral (floatRadix t) ^ floatDigits t

fromFraction :: Num b => Fraction a -> b Source

lifted fromIntegral

Instances

class KnownNat n => Radix n where Source

Methods

isDigit :: proxy n -> Word8 -> Bool Source

check input Word8 is digit charactor or not.

unsafeToDigit :: proxy n -> Word8 -> Word8 Source

convert digit charactor to number. undefined behaviour when give non-digit charactor.
