Template:Str number/doc

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.

Examples

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
