SignPadding

SignPadding

is an option for NumberForm and related functions that specifies whether padding should be inserted after signs.

Details

  • SignPaddingTrue specifies that any padding that is needed should be inserted between the sign and the digits in a number.
  • SignPaddingFalse specifies that the padding should be inserted outside the sign.
  • Different sign characters can be present to the left and right of the number, as specified by the option NumberSigns. Padding strings on either side of the number are given by NumberPadding{"sleft","sright"}. Whether those padding strings are placed inside the corresponding signs is given by SignPadding{lbool,rbool}.

Basic Examples  (2)

The default pads before signs:

Wolfram Language code: NumberForm[{-1.23, 2.46}, 5, NumberPadding -> {" ", " "}]

Pad between signs and numbers instead:

Wolfram Language code: NumberForm[{-1.23, 2.46}, 5, SignPadding -> True, NumberPadding -> {" ", " "}]

Scope  (2)

Use SignPadding with PaddedForm:

Wolfram Language code: PaddedForm[{-1.23, 2.46}, 5, SignPadding -> True, NumberPadding -> {" ", ""}]

EngineeringForm:

Wolfram Language code: EngineeringForm[{-1.23, 2.46}, 5, SignPadding -> True, NumberPadding -> {" ", ""}]

ScientificForm:

Wolfram Language code: ScientificForm[{-1.23, 2.46}, 5, SignPadding -> True, NumberPadding -> {" ", ""}]

AccountingForm:

Wolfram Language code: AccountingForm[{-1.23, 2.46}, 5, SignPadding -> True, NumberPadding -> {" ", ""}]

PercentForm by default pads before the – and % signs:

Wolfram Language code: PercentForm[-0.001234``6, {8, 5}, NumberPadding -> {" ", "*"}]

Pad inside the signs:

Wolfram Language code: PercentForm[-0.001234``6, {8, 5}, NumberPadding -> {" ", "*"}, SignPadding -> {True, True}]

Pad after the signs:

Wolfram Language code: PercentForm[-0.001234``6, {8, 5}, NumberPadding -> {" ", "*"}, SignPadding -> {True, False}]

Pad outside the signs:

Wolfram Language code: PercentForm[-0.001234``6, {8, 5}, NumberPadding -> {" ", "*"}, SignPadding -> {False, False}]
