Method Description abs(x) Returns the absolute value of x acos(x) Returns the arccosine of x, in radians asin(x) Returns the arcsine of x, in radians atan(x) Returns the arctangent of x as a numeric value between -PI/2 and PI/2 radians atan2(y, x) Returns the arctangent of the quotient of its arguments ceil(x) Returns x, rounded upwards to the nearest integer cos(x) Returns the cosine of x (x is in radians) exp(x) Returns the value of E x floor(x) Returns x, rounded downwards to the nearest integer log(x) Returns the natural logarithm (base E) of x max(x, y, z, ..., n) Returns the number with the highest value min(x, y, z, ..., n) Returns the number with the lowest value pow(x, y) Returns the value of x to the power of y random() Returns a random number between 0 and 1 round(x) Rounds x to the nearest integer sin(x) Returns the sine of x (x is in radians) sqrt(x) Returns the square root of x tan(x) Returns the tangent of an angle 參考資料： http://www.w3schools.com/js

null表示沒有值，可以賦值給a。 undefined則表示不給值或是不初始化。  a = null;  a = undefined;  物件是名稱和值為組的群集  var mouse = { eyes: "Blue", big:true } 物件屬性可以用.或是[]存取 函式與物件結合叫做方法 a.do(1,2,3) 建構式的開頭大寫 function Push(a,b){ a*b; }
