public function decToInt32TrueError(input, output, startpos, endpos) result(error)Parse the input string as a signed decimal integer string to an int32 value.
This function ignores leading and trailing whitespaces.
This function return an int32 value of 0 on successful parse cases or a true error code on unsuccessful parse cases.
Error codes:
0 - none
1 - empty strings
2 - invalid format
