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.
