EXAMPLES

Given a locale for the U.S. and the values 123.45, -123.45, and 3456.781,
the following output might be produced. Square brackets ( "[]" ) are used
in this example to delimit the output.

 
%n         [$123.45]         Default formatting 
           [-$123.45]
           [$3,456.78]

%11n       [    $123.45]     Right align within an 11-character field 
           [   -$123.45]
           [  $3,456.78]

%#5n       [ $   123.45]     Aligned columns for values up to 99999 
           [-$   123.45]
           [ $ 3,456.78]

%=*#5n     [ $***123.45]     Specify a fill character 
           [-$***123.45]
           [ $*3,456.78]

%=0#5n     [ $000123.45]     Fill characters do not use grouping 
           [-$000123.45]     even if the fill character is a digit 
           [ $03,456.78]

%^#5n      [ $  123.45]      Disable the grouping separator 
           [-$  123.45]
           [ $ 3456.78]

%^#5.0n    [ $  123]         Round off to whole units 
           [-$  123]
           [ $ 3457]

%^#5.4n    [ $  123.4500]    Increase the precision 
           [-$  123.4500]
           [ $ 3456.7810]

%(#5n      [$   123.45]      Use an alternative pos/neg style 
           [($   123.45)]
           [$ 3,456.78]

%!(#5n     [   123.45]       Disable the currency symbol 
           [(   123.45)]
           [ 3,456.78]

%-14#5.4n  [ $   123.4500 ]  Left-justify the output 
           [-$   123.4500 ]
           [ $ 3,456.7810 ]

%14#5.4n   [  $   123.4500]  Corresponding right-justified output 
           [ -$   123.4500]
           [  $ 3,456.7810]
