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[redigér wikikode]

To render 3.14 × 10−12, instead of writing 3.14&nbsp;×&nbsp;10<sup>&minus;12</sup> you can write 3.14{{e|-12}}:


{{10^|b}} → 10b

{{10^|-12}} → 1012

The first output character for {{e}} is a non-breaking thin-space:

.{{e|b}}. → .×10b.

.{{10^|b}}. → .10b.

.{{10^|-12}}. → .1012.

Delimiters[redigér wikikode]

The template uses gaps or commas, per {{val/delimitnum}}.

See #Forcing text display to turn this off.

Text and number recognition[redigér wikikode]

By default, the template recognizes both text and numbers. That is, typing 3.14{{e|-12}} will produce 3.14×1012, 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|&minus;BC}} to produce the correct A×10−BC.

A minus sign also has to be provided for cases like 1.2×101 − 2 (1.2{{e|1 &minus; 2}}).

Explicit plus sign[redigér wikikode]

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

Forcing text display[redigér wikikode]

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 1.2×1042342. 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.

Tracking category[redigér wikikode]

Category:Articles using E without any arguments is a hidden category which may be added to pages using Template:E.
