ParseInt()
|
var i = parseInt(number1); var j = parseInt(number2); var k = parseInt(number3); var l = parseInt(number4); |

Using unary

var i = +number1; var j = +number2; var k = +number3; var l = +number4; |

By multplication
|
var i = number1 * 1; var j = number2 * 1; var k = number3 * 1; var l = number4 * 1; |
