NumberPadding

  • NumberPadding is an option for NumberForm and related functions which gives strings to use as padding on the left- and right-hand sides of numbers.
  • NumberPadding -> " sleft ", " sright " specifies strings to use for padding on the left and right.
  • In NumberForm, the default setting is NumberPadding -> {"", ""}.
  • In PaddedForm, the default setting is NumberPadding -> {" ", "0"}.
  • The strings specified as padding are inserted in place of digits.
  • See the Mathematica book: Section 2.8.7.
  • See also: SignPadding.

    Further Examples

    With the default setting for the option NumberPadding, both NumberForm and PaddedForm insert trailing zeros when they pad a number on the right. You can use spaces for padding on both the left and the right by setting NumberPadding -> {" ", " "}.
