1. showFFloatAlt :: RealFloat a => Maybe Int -> a -> ShowS

   base-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.

2. showGFloatAlt :: RealFloat a => Maybe Int -> a -> ShowS

   base-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.

3. showHFloat :: RealFloat a => a -> ShowS

   base-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"
   

4. showException :: Show e => e -> IO String

   extra	Control.Exception.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.

5. showDP :: RealFloat a => Int -> a -> String

   extra	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"
   

6. showDuration :: Seconds -> String

   extra	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"
   

7. showException :: Show e => e -> IO String

   extra	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.

8. showDP :: RealFloat a => Int -> a -> String

   extra	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"
   

9. showDuration :: Seconds -> String

   extra	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"
   

10. showsInfixPrec :: (Show a, Show b) => String -> Int -> Int -> a -> b -> ShowS

    utility-ht	Text.Show.HT

    Show a value using an infix operator.
