NumberForm

Usage

• NumberForm[expr, n] prints with approximate real numbers in expr given to n-digit precision.

Notes

• NumberForm[expr, {n, f}] prints with approximate real numbers having n digits, with f digits to the right of the decimal point.

• NumberForm works on integers as well as approximate real numbers.

• The following options can be given:

DigitBlock	Infinity	number of digits between breaks
ExponentFunction	Automatic	function to apply to exponents
NumberFormat	Automatic	function used to assemble mantissa, base, exponent
NumberMultiplier	""	string to use to indicate multiplication
NumberPadding	{"", ""}	strings to use for left and right padding
NumberPoint	"."	decimal point string
NumberSeparator	","	string to insert at breaks between blocks
NumberSigns	{"-", ""}	strings to use for signs of negative and positive numbers
SignPadding	False	whether to insert padding after the sign

• All options except ExponentFunction apply to integers as well as approximate real numbers.

• You can mix NumberForm and BaseForm.

• NumberForm acts as a "wrapper", which affects printing, but not evaluation.
