Template:Iszero
{{iszero}} returns the passed value if it evaluates as non-zero. If it is zero, by default the template returns nothing, or it can return any other value you specify. Blank inputs are treated as zeros by default, but that can be overridden.
| Tip:
|
Non-numeric text generally will evaluate as non-zero, so you may want to pass the input value through {{isnumeric}} first (see examples 12 and 14) and treat non-numeric text as a blank. |
