8727 Convert string {expr} to a number. 8756 Convert string {expr} to a number.
8728 {base} is the conversion base, it can be 2, 8, 10 or 16. 8757 {base} is the conversion base, it can be 2, 8, 10 or 16.
8729 When {base} is omitted base 10 is used. This also means that 8758 When {base} is omitted base 10 is used. This also means that
