ParseInt() in radix mode

The parseInt() method also has a radix mode, allowing you to convert strings in binary, octal, hexadecimal, or any other base into an integer. The radix is specified as a second argument to parseInt(). var iNum1 = parseInt("AF", 16); var iNum1 = parseInt("10", 2); var iNum2 = parseInt("10", 8); var iNum2 = parseInt("10", 10);
