octalInt64OrSmaller Function

public pure function octalInt64OrSmaller(firstString, secondString) result(int32Out)

Compare two strings bases on the content of the strings reference to int64 values. If the strings are valid octal strings that can be parsed to int64 values then they will be compared base on their int64 values. Otherwise, the strings will be compared base on the priority ranking order below.

This function return an int32 value of 1 if the firstString is larger than the secondString, 0 if they are both equal, or -1 if the firstString is smaller than the secondString.

Priority order ranking: (lo - hi) 0 - invalid format
1 - value too large for data type
2 - empty string (0 length or empty space)
3 - valid int64
