Basic Examples  (2)

Three numbers in scientific form:

The same numbers to 3 precise digits:

Scope  (5)

The default display for a machine number:

Display more digits than the default:

Display fewer digits:

Format a complex number:

Format a high-precision number:

Use fewer digits:

Change the display of numbers in a vector:

A matrix:

Change the display of inexact numbers in a mixed expression:

Use 4 precise digits:

Options  (11)

DigitBlock  (2)

A default integer:

Digits separated in blocks of length 3:

Use fivedigit blocks with spaces as separators:

ExponentFunction  (1)

Compute approximate powers of :

Restrict exponents to multiples of 3:

Include exponents only for powers greater than 10:

ExponentStep  (1)

Default formatting to 10 digits:

Restrict exponent to multiples of 6:

NumberFormat  (1)

Display numbers in a Fortranlike form:

Display only the mantissas:

Display only the exponents:

NumberMultiplier  (1)

Use the default multiplier ×:

Use an asterisk (*) instead:

NumberPadding  (1)

The default does not pad on the left or right:

Pad with spaces on the left:

NumberPoint  (1)

The default is a period:

Display with a comma (,) instead:

NumberSeparator  (1)

The default separator is a comma (,):

Use spaces instead:

NumberSigns  (1)

The default includes negative signs but not positive signs:

Include positive signs as well:

Use words instead of symbols:

SignPadding  (1)

The default pads before signs:

Pad between signs and numbers instead:

Properties & Relations  (5)

ScientificForm has a single digit to the left of the decimal by default:

NumberForm and PaddedForm include exponents higher than 5 by default:

EngineeringForm uses exponents that are multiples of 3:

AccountingForm does not have exponents:

Convert a number to base 2:

Represent the number in base 2:

Reconstruct the base 10 number:

Affect the display of numbers in MatrixForm or TableForm:

The typeset form of ScientificForm[expr] is interpreted the same as expr when used in input:

Copy the output and paste it into an input cell. The 1.23×102 is interpreted as 123.:

When an input evaluates to ScientificForm[expr], ScientificForm does not appear in the output:

Out is assigned the value 123., not ScientificForm[123.]:

Possible Issues  (2)

Placeholder zeros may be needed if the requested precision is small:

Even when an output omits ScientificForm from the top level, it is not stripped from subexpressions:

The output does not have ScientificForm in it:

However, the variable e does have ScientificForm in it, which may affect subsequent evaluations:

The product is not evaluated due to the intervening ScientificForm:

Assign variables first and then apply ScientificForm to the result to maintain computability:
