1. showBin :: Integral a => a -> ShowS

   base	Numeric

   Show non-negative Integral numbers in base 2.

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

   base	Numeric

   Show a signed RealFloat value using scientific (exponential) notation (e.g. 2.45e2, 1.5e-3). In the call showEFloat digs val, if digs is Nothing, the value is shown to full precision; if digs is Just d, then at most d digits after the decimal point are shown.

3. showFFloat :: RealFloat a => Maybe Int -> a -> ShowS

   base	Numeric

   Show a signed RealFloat value using standard decimal notation (e.g. 245000, 0.0015). In the call showFFloat digs val, if digs is Nothing, the value is shown to full precision; if digs is Just d, then at most d digits after the decimal point are shown.

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

   base	Numeric

   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.

5. showFloat :: RealFloat a => a -> ShowS

   base	Numeric

   Show a signed RealFloat value to full precision using standard decimal notation for arguments whose absolute value lies between 0.1 and 9,999,999, and scientific notation otherwise.

6. showGFloat :: RealFloat a => Maybe Int -> a -> ShowS

   base	Numeric

   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. In the call showGFloat digs val, if digs is Nothing, the value is shown to full precision; if digs is Just d, then at most d digits after the decimal point are shown.

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

   base	Numeric

   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.

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

   base	Numeric

   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"
   

9. showHex :: Integral a => a -> ShowS

   base	Numeric

   Show non-negative Integral numbers in base 16.

10. showInt :: Integral a => a -> ShowS

    base	Numeric

    Show non-negative Integral numbers in base 10.
