Number.MAX_VALUE

¥Value

2¹⁰²⁴ - 2⁹⁷¹，或大约 1.7976931348623157E+308。

¥2¹⁰²⁴ - 2⁹⁷¹, or approximately 1.7976931348623157E+308.

¥Description

大于 MAX_VALUE 的值将表示为 Infinity，并将丢失其实际值。

¥Values larger than MAX_VALUE are represented as Infinity and will lose their actual value.

由于 MAX_VALUE 是 Number 的静态属性，因此你始终将其用作 Number.MAX_VALUE，而不是作为数字值的属性。

¥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.

¥Examples

¥Using MAX_VALUE

以下代码将两个数值相乘。如果结果小于或等于 MAX_VALUE，则调用 func1 函数；否则，调用 func2 函数。

¥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();
}
