Description
Returns the integer represented by the characters of string in the number base base, where base is between 2 and 36. You can constrain the search to a substring of string by giving values for start and end.
This function returns the next key beyond the last character it examines.
If there is no integer contained in the specified region of the string, this function returns default, if specified. If you do not give a value for default, this function signals an error.
This function is similar to C's strtod function.
