Template:E

Template documentation[view] [edit] [history] [purge]

The {{e}} and {{10^}} templates are intended to facilitate and make uniform scientific notation numbers. The {{10^}} template works exactly as described below except that it does not generate a multiplication (“×”) symbol.

Usage

To render 3.14×10⁻¹², instead of writing 3.14 × 10^−12 you can write 3.14{{e|-12}}:

{{e|b}} → ×10^b

{{10^|b}} → 10^b

{{e|-12}} → ×10⁻¹²

{{10^|-12}} → 10⁻¹²

The first output character for {{e}} is a non-breaking thin-space (“]” and “[” are used to illustrate the effects):

]{{e|b}}[ → ]×10^b[

]{{10^|b}}[ → ]10^b[

]{{e|-12}}[ → ]×10⁻¹²[

]{{10^|-12}}[ → ]10⁻¹²[

Delimiters

The template uses gaps or commas, per {{val/delimitnum}}.
1.2{{e|12341}} → 1.2×10¹²³⁴¹

See #Forcing text display to turn this off.

Text and number recognition

By default, the template recognizes both text and numbers. That is, typing 3.14{{e|-12}} will produce 3.14×10⁻¹², with the proper minus sign (“−”), rather than with a hyphen (“-”). However, typing A{{e|-BC}} will produce A×10^-BC since BC is not a number. In those cases, you need to write A{{e|−BC}} to produce the correct A×10^−BC.

A minus sign also has to be provided for cases like 1.2×10^{1 − 2} (1.2{{e|1 − 2}}).

Explicit plus sign

To explicitly display the + character, write 1.2{{e|4|plus}} which will produce 1.2×10⁺⁴.

Forcing text display

To force the template to display the input as text, and forgo the automatic delimitation and the recognition of the hyphen as a minus sign, write 1.2{{e|−42342|text}}, which will display 1.2×10⁻⁴²³⁴² instead of 1.2×10⁻⁴²³⁴². This can also be used as an alternative to explicitly display the plus sign (1.2{{e|+4|text}} gives 1.2×10⁺⁴), but remember that you also lose delimitation if you do it this way.
