public function fnStringCompareAsBase(firstString, secondString, base, output) result(error)Compare two strings as integer strings of a numbering system with the radix that is defined by the value of the argument base. There isn't a maximum length for the strings. Nonetheless, the strings can't be empty.
This function support numbering system with radix from 2 to 36. This function evaluates both, negative and positive values.
This function ignores leading and trailing whitespaces.
This function disregards leading zeroes.
This function return an int32 value of 0 if it did not encounter an error during the comparison process. Otherwise, it will return a true error code.
Error code:
0 - no error
1 - empty firstString
2 - empty secondString
3 - bad format firstString
4 - bad format secondString
5 - base < 2 or base > 36
