Template:Isnumeric/doc

此模板测试给定值是否为数字 (or at least, that it can be treated as such by the expression ParserFunction).

使用

By default, simply writing {{Isnumeric|1,327}} (where 1,327 is an example number) will pass through the parameter if it's numeric and be blank if it's not. If the parameter boolean=true is given, as in {{Isnumeric|1,327|boolean=true}}, then the template will output 1 if numeric and 0 if not numeric.

示例

code	result
{{Isnumeric|1,327.50}}	1,327.50
{{Isnumeric|9,999 (1950)}}
{{Isnumeric|9999999999999}}	9999999999999
{{Isnumeric|500 metres}}
{{Isnumeric|500*500}}	500*500
{{Isnumeric|9.999e50}}	9.999e50
