Template:Isnumeric
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.
