Template:E/doc

This is a documentation subpage for Template:E.
It contains usage information, categories and other informational content that is best arranged so that it is not part of the original template page, such as in many cases, examples of how to use the template in question. Documentation subpages were developed to reduce server demands, or to protect the code version of widely used templates.

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.

Basic usage

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

Delimitation

The template uses the delimitation logic of the {{val}} template. That is, typing 1.2{{e|12341}} will produce a delimited exponent (1.2×10^12,341). 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^−42,342. 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.
