Template:Esp/doc

Usage
The Esp template is intended to facilitate and make uniform scientific notation numbers. Its is a spaced version of e template. To render
 * 3.14🇪🇸

instead of writing:
 *  3.14&amp;nbsp;×&amp;nbsp;10−12 

you can write:
 *  3.14🇪🇸 

which yields that same wikitext, and is therefore rendered the same.

Note that the parameter is text, not a number; it can include variables which can be italicized, etc. This also means that using a hyphen (-) and a minus sign (&minus;) with negative numbers gives different results.
 *  3.14🇪🇸 &mdash;3.14🇪🇸
 *  3.14🇪🇸 &mdash;3.14🇪🇸
 *  3.14🇪🇸 &mdash;3.14🇪🇸
 *  3.14🇪🇸 &mdash;3.14🇪🇸
