{{User:Johan G/convert/rear}}: Parameter expression missing
The following template description is not displayed when the template is inserted in an article.
Goal
This template handles rounding, decimals and units for User:Johan G/convert ("rear" is for rear part of the quantity).
Note When this template draft is moved to the template namespace, give it a better name...
Usage
{{User:Johan G/convert/rear|expression|to-unit|decimals|hide-unit}}
The parameters expression and to-unit is manatory, though all parameters should be passed from the main template.
- expression
- Expression to be calculated with Extension:ParserFunctions's #expr function
- to-unit
- Unit to be converted to
- decimals
- Number of decimals. If empty, no decimals will be shown
- hide-unit
- If not empty the unit will not be shown in the result
Examples
Conversion from millimeters to inches as it would be used in the main template...
{{User:Johan G/convert/rear|{{{1}}} div 25.4|in|{{{4|}}}|{{{5|}}}}}
...with the parameters having these values
{{User:Johan G/convert/rear|1000 div 25.4|in|2|}}
39.37 in
Known issues
Trailing zeros in the decimals will not be shown.
