This is the {{قا|Str number}} meta-template.

It takes a string as parameter, and returns the number of leading digits. It can count up to 25, and returns 25 if there are more.

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

:<code><nowiki>{{str number}}</nowiki></code> returns {{str number}}
:<code><nowiki>{{Str number|}}</nowiki></code> returns {{Str number|}}
:<code><nowiki>{{Str number| }}</nowiki></code> returns {{Str number| }}

The count is interrupted by anything but the ten digits:

:<code><nowiki>{{Str number|abcde}}</nowiki></code> returns {{Str number|abcde}}
:<code><nowiki>{{Str number|123456}}</nowiki></code> returns {{Str number|123456}}
:<code><nowiki>{{Str number|123 456}}</nowiki></code> returns {{Str number|123 456}}
:<code><nowiki>{{Str number|1234abc}}</nowiki></code> returns {{Str number|1234abc}}
:<code><nowiki>{{Str number|1234abc56}}</nowiki></code> returns {{Str number|1234abc56}}

If there are more than 24 leading digits, 25 is returned:

:<code><nowiki>{{Str number|123456789012345678901234}}</nowiki></code> returns {{Str number|123456789012345678901234}}
:<code><nowiki>{{Str number|1234567890123456789012345}}</nowiki></code> returns {{Str number|1234567890123456789012345}}
:<code><nowiki>{{Str number|12345678901234567890123456}}</nowiki></code> returns {{Str number|12345678901234567890123456}}
:<code><nowiki>{{Str number|123456789012345678901234a}}</nowiki></code> returns {{Str number|123456789012345678901234a}}
:<code><nowiki>{{Str number|1234567890123456789012345a}}</nowiki></code> returns {{Str number|1234567890123456789012345a}}
:<code><nowiki>{{Str number|12345678901234567890123456a}}</nowiki></code> returns {{Str number|12345678901234567890123456a}}

The maximum is reduced if the template is called in a template parameter:
:<code><nowiki>{{1x|{{Str number|1234567890123456789012345}}}}</nowiki></code> returns {{1x|{{Str number|1234567890123456789012345}}}}
This is caused by the template depth limit (the character in a specific position of the given string is determined only if the preceding characters are all digits, hence the parser functiions are nested): if the result of finding the character in a specific position of the given string is an expansion depth error message, this message is not a digit.
