Number parsing
ACSUtils provides functions to convert strings to numbers.
Simple functions
These simply return 0 on error:
atoi("123") -> 123
atof("123.456") -> 123.456
atoi("abc") -> 0
Complex functions
These return error status and result, and allow specifying an arbitrary base:
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.
