Synopsis

Read/show for numeric strings

Natural

showNatural :: DigitStringSuperset string => Natural -> string Source #

Examples:

  • showNatural 0 = "0"
  • showNatural 268 = "268"

readNatural :: DigitStringSuperset string => string -> Maybe Natural Source #

Examples:

  • readNatural "0" = Just 0
  • readNatural "268" = Just 268
  • readNatural "0004" = Just 4
  • readNatural "" = Nothing
  • readNatural "-4" = Nothing
  • readNatural "12345678901234567890" = Just 12345678901234567890

Integer

showInteger :: StringSuperset string => Integer -> string Source #

Examples:

  • showInteger 0 = "0"
  • showInteger 12 = "12"
  • showInteger (negate 12) = "-12"

readInteger :: StringSuperset string => string -> Maybe Integer Source #

Examples:

  • readInteger "0" = Just 0
  • readInteger "268" = Just 268
  • readInteger "0004" = Just 4
  • readInteger "" = Nothing
  • readInteger "-4" = Just (-4)
  • readInteger "12345678901234567890" = Just 12345678901234567890

Integral

showIntegral :: (Integral n, StringSuperset string) => n -> string Source #

readIntegral :: (StringSuperset string, Integral num, Bits num) => string -> Maybe num Source #

Examples:

  • readIntegral "0" = Just (0 :: Word8)
  • readIntegral "175" = Just (175 :: Word8)
  • readIntegral "268" = (Nothing :: Maybe Word8)
  • readIntegral "0004" = Just (4 :: Word8)
  • readIntegral "" = (Nothing :: Maybe Word8)
  • readIntegral "-4" = (Nothing :: Maybe Word8)
  • readIntegral "12345678901234567890" = (Nothing :: Maybe Word8)
