ACSUtils provides functions to convert strings to numbers.

These simply return 0 on error:

• atoi
• atof

atoi("123") -> 123
atof("123.456") -> 123.456
atoi("abc") -> 0

These return error status and result, and allow specifying an arbitrary base:

• ParseInt
• ParseFixed

Error statuses are:

• PARSENUMBER_SUCCESS – number successfully parsed, you can use the result
• PARSENUMBER_OVERFLOW – the number is too big to fit into a variable, the result will be either INT_MAX or INT_MIN.
• PARSENUMBER_BADFORMAT - the number could not be parsed at all. You may not use the result. r2 is unchanged.
