The parseInt method parses a value as a string and returns the first integer. A radix parameter specifies the number system to use: 2 = binary, 8 = octal, 10 = decimal, 16 = hexadecimal. If radix is omitted, JavaScript assumes radix 10. If the value begins with "0x", JavaScript assumes radix 16.

Example. Parse different strings: var a = parseInt ("10") + "<br>"; var b = parseInt ("10.00") + "<br>"; var c = parseInt ("10.33") + "<br>"; var d = parseInt ("34 45 66") + "<br>"; var e = parseInt (" 60 ") + "<br>"; var f = parseInt ("40 years") + "<br>"; var g = parseInt ("He was 40") + "<br>";
