The Number.MAX_VALUE
static data property represents the maximum numeric value representable in JavaScript.
function multiply(x, y) {
if (x * y > Number.MAX_VALUE) {
return "Process as Infinity";
}
return x * y;
}
console.log(multiply(1.7976931348623157e308, 1));
// Expected output: 1.7976931348623157e+308
console.log(multiply(1.7976931348623157e308, 2));
// Expected output: "Process as Infinity"
Value
21024 - 2971, or approximately 1.7976931348623157E+308
.
Values larger than MAX_VALUE
are represented as Infinity
and will lose their actual value.
Because MAX_VALUE
is a static property of Number
, you always use it as Number.MAX_VALUE
, rather than as a property of a number value.
The following code multiplies two numeric values. If the result is less than or equal to MAX_VALUE
, the func1
function is called; otherwise, the func2
function is called.
if (num1 * num2 <= Number.MAX_VALUE) {
func1();
} else {
func2();
}
