* Write your own Math.pow(a int, b int) function **/function pow (a, b) { let result=0; let nigate= b <0; b= nigate ? b*(-1) : b;if(b ===0) { result=1; } let isEven= b %2===0;if(b ===1) { result=a; }if(b >=2) {
Power Function:在某些上下文中,pow函数可以被视为一种幂函数,尽管幂函数通常指的是形式为f(x) = x^n的函数,其中n是常数。 Explanation: A power function, in a broader sense, can be seen as a function of the form f(x) = x^n, where n is a constant. Although pow is more specific, it p...

javascript 指数为整数 Math.pow 指数为整数 Math.ipow = function(x, y) { if (0==y) return 1; // else return x * pow(x, y-1); var res = 1; for (; y != 0; y>>=1) { if ((y&1) != 0) { res *= x; } x = x * x;...
So with CSS thehypot()function (and in JavaScript with theMath.hypot()method), we can pass in an arbitrary amount of parameters. The function will then square all the parameters, add them together, and take the square root. animation-iteration-count:hypot(2);/* 2 */ ...

但是当我们写一个函数时，幂运算又表现出诡异的特性：function diff(x) { return Math.pow(x,x) - x**x;}调用 diff(99) 返回 。WTF？两者又相等了！猜猜下面代码输出什么？var x = 99;x**x - 99**99;这段代码的运行结果是 -5.311379928167671e+182。这简直是薛定谔的幂。究其原因，V8 引擎使用...
