showException :: Show e => e -> IO Stringextra Extra Show a value, but if the result contains exceptions, produce <Exception>. Defined as stringException . show. Particularly useful for printing exceptions to users, remembering that exceptions can themselves contain undefined values.
showDP :: RealFloat a => Int -> a -> Stringextra Numeric.Extra Show a number to a fixed number of decimal places.
showDP 4 pi == "3.1416" showDP 0 pi == "3" showDP 2 3 == "3.00"
showDuration :: Seconds -> Stringextra System.Time.Extra Show a number of seconds, typically a duration, in a suitable manner with reasonable precision for a human.
showDuration 3.435 == "3.44s" showDuration 623.8 == "10m24s" showDuration 62003.8 == "17h13m" showDuration 1e8 == "27777h47m"
showBin :: Integral a => a -> ShowSbase-compat Numeric.Compat Show non-negative Integral numbers in base 2.
showFFloatAlt :: RealFloat a => Maybe Int -> a -> ShowSbase-compat Numeric.Compat Show a signed RealFloat value using standard decimal notation (e.g. 245000, 0.0015). This behaves as showFFloat, except that a decimal point is always guaranteed, even if not needed.
showGFloatAlt :: RealFloat a => Maybe Int -> a -> ShowSbase-compat Numeric.Compat Show a signed RealFloat value using standard decimal notation for arguments whose absolute value lies between 0.1 and 9,999,999, and scientific notation otherwise. This behaves as showFFloat, except that a decimal point is always guaranteed, even if not needed.
showHFloat :: RealFloat a => a -> ShowSbase-compat Numeric.Compat Show a floating-point value in the hexadecimal format, similar to the %a specifier in C's printf.
>>> showHFloat (212.21 :: Double) "" "0x1.a86b851eb851fp7" >>> showHFloat (-12.76 :: Float) "" "-0x1.9851ecp3" >>> showHFloat (-0 :: Double) "" "-0x0p+0"
showsInfixPrec :: (Show a, Show b) => String -> Int -> Int -> a -> b -> ShowSutility-ht Text.Show.HT Show a value using an infix operator.
showsPrecDefault :: (GShow (Rep1 f a), Generic1 f) => Int -> f a -> ShowStransformers-compat Data.Functor.Classes.Generic.Internal A default showsPrec implementation for Generic1 instances that leverages Show1.
showsPrecOptions :: (GShow (Rep1 f a), Generic1 f) => Options -> Int -> f a -> ShowStransformers-compat Data.Functor.Classes.Generic.Internal Like showsPrecDefault, but with configurable Options.
