This is the {{str number}} meta-template.

It takes a string as parameter, and returns the number of leading digits. It does not handle negative numbers or decimals, and stops at any minus sign '-' or dot '.' symbols.

If the parameter is empty or undefined, zero is returned:

{{str number}} returns 0
{{str number|}} returns 0
{{str number| }} returns 0

The count is interrupted by anything but the ten digits:

{{str number|abcde}} returns 0
{{str number|123456}} returns 6
{{str number| 123456}} returns 6
{{str number|123 456}} returns 3
{{str number|1234abc}} returns 4
{{str number|1234abc56}} returns 4
{{str number|15<ref>a reference</ref>}} returns 2
{{str number|15(15)}} returns 2
{{str number|-1234xx}} returns 0
{{str number|12.34xx}} returns 2
