Math.max Function (JavaScript)

The optional number1, number2, ..., numberN arguments are numeric expressions to be evaluated.

If no arguments are provided, the return value is equal to Number.NEGATIVE_INFINITY. If any argument is NaN, the return value is also NaN.

The following code shows how to get the larger of two expressions.

var x = Math.max(107 - 3,  48 * 90);
document.write(x);

// Output:
// 4320
