JavaScript |数学对象
Math 对象用于对数字执行数学运算。下面列出了许多数学对象属性：
| Property | Description |
|---|---|
| Math.E | Euler’s number |
| Math.PI | PI |
| Math.SQRT2 | The square root of 2 |
| Math.SQRT1_2 | The square root of 1/2 |
| Math.LN2 | The natural logarithm of 2 |
| Math.LN10 | The natural logarithm of 10 |
| Math.LOG2E | Base 2 logarithm of E |
| Math.LOG10E | Base 10 logarithm of E |
数学对象： JavaScript 中存在许多数学对象，如下所列：
| Property | Description |
|---|---|
| abs(x) | Absolute value of x |
| acos(x) | Arccosine of x, in radian |
| asin(x) | Arcsine of x, in radian |
| atan(x) | Arctangent of x, a numeric value between -PI/2 and PI/2 radian |
| atan2(y, x) | Arctangent of the quotient of its arguments |
| ceil(x) | Value of x rounded up to the nearest integer |
| cos(x) | Cosine of x (x in radians) |
| exp() | Value of E^x |
| floor() | Value of x rounded below to the nearest integer |
| log() | Natural logarithm (base E) of x |
| max(a, b, …) | Highest value |
| min(a, b, …) | Lowest value |
| pow(x, y) | Value of x to power of y |
