টেমপ্লেট:Str number
0
This is the {{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.
উদাহরণ
[সম্পাদনা]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
If there are more than 24 leading digits, 25 is returned:
{{str number|123456789012345678901234}}returns 24{{str number|1234567890123456789012345}}returns 25{{str number|12345678901234567890123456}}returns 26{{str number|123456789012345678901234a}}returns 24{{str number|1234567890123456789012345a}}returns 25{{str number|12345678901234567890123456a}}returns 26
The maximum is reduced if the template is called in a template parameter:
{{1x|{{str number|1234567890123456789012345}}}}returns 25
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.
