This is a documentation subpage for Template:E. It contains usage information, categories and other content that is not part of the original template page. |
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.
Contents
Usage[edit]
To render Template:Xt, instead of writing Template:Xt you can write Template:Xt:
{{#invoke:DemoTemplate|e|b}}
{{#invoke:DemoTemplate|10^|b}}
{{#invoke:DemoTemplate|10^|-12}}
The first output character for {{e}} is a non-breaking thin-space:
.{{e|b}}. → .×10Template:Val/delimitnum.
.{{10^|b}}. → .Template:10^.
.{{10^|-12}}. → .Template:10^.
Delimiters[edit]
The template uses gaps or commas, per {{val/delimitnum}}.
Template:Xt → Template:Xt.
See #Forcing text display to turn this off.
Text and number recognition[edit]
By default, the template recognizes both text and numbers. That is, typing Template:Xt will produce Template:Xt, with the proper minus sign (Template:Xt), rather than with a hyphen (Template:Xt). However, typing Template:Xt will produce Template:Xt since Template:Xt is not a number. In those cases, you need to write Template:Xt to produce the correct Template:Xt.
A minus sign also has to be provided for cases like Template:Xt (Template:Xt).
Explicit plus sign[edit]
To explicitly display the Template:Xt character, write Template:Xt which will produce Template:Xt.
Forcing text display[edit]
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 Template:Xt, which will display Template:Xt instead of Template:Xt. This can also be used as an alternative to explicitly display the plus sign (Template:Xt gives Template:Xt), but remember that you also lose delimitation if you do it this way.
Tracking category[edit]
Category:Articles using E without any arguments is a hidden category which may be added to pages using Template:E.
