An explanation of the new math and Number methods in JavaScript ES6

The new math and Number methods in ES6, I think they are very good. Friends who need them can refer to them.

The new math and Number methods in ES6 are summarized below. Some of them I think are useful

Nunber.isInteger() determines whether it is an integer. It should be noted that 1 and 1.0 will be considered integers

##

console.log(Number.isInteger(1.0))//true
console.log(Number.isInteger(1))//true
console.log(Number.isInteger("1"))//false
console.log(Number.isInteger("1.1"))//false

Math.sign() Determine whether it is a positive number, a negative number, or 0

##

console.log(Math.sign(1))//1
console.log(Math.sign(-1))//-1
console.log(Math.sign(0))//0
console.log(Math.sign(-0))//0
console.log(Math.sign(NaN))//NaN
console.log(Math.sign(undefined))//NaN
console.log(Math.sign(null))//0

Math.cbrt() calculates the cube root of a number

console.log(Math.cbrt(8))//2
Math.hypot()返回所有参数的平方和的平方根
console.log(Math.hypot(4,3))//25再开方结果为5

Exponential operation

console.log(2**2) //4     
console.log(2**3) //8
