NumberSigns

  • NumberSigns is an option for NumberForm and related functions which gives strings to use as signs for negative and positive numbers.
  • NumberSigns -> " sneg ", " spos " specifies that " sneg " should be given as the sign for negative numbers, and " spos " for positive numbers.
  • The default setting is NumberSigns -> {"-", ""}.
  • NumberSigns -> " snleft ", " snright " , " spleft ", " spright " specifies strings to put both on the left and right of numbers to specify their signs.
  • In AccountingForm, the default setting is NumberSigns -> {{"(", ")"}, ""}.
  • See the Mathematica book: Section 2.8.7.
  • See also: SignPadding.

    Further Examples

    This breaks digits into blocks of length 3.

    In[1]:=

    Out[1]//NumberForm=

    You can specify any string to use as a separator between blocks of digits.

    In[2]:=

    Out[2]//NumberForm=

    This gives an explicit plus sign for positive numbers, and uses | in place of a decimal point.

    In[3]:=

    Out[3]//NumberForm=
