The JS function for math arithmetic

Random function; Moth.random ()

            // 3, the following through the loop to each element of the array assignment, random number.             //  math.random (); Can randomly 0~1 any number between  [0,1]            //  alert (Math.random ());                             /* integer between Random 0~10 (can be random to 0 but not at random), parseint (Math.random (              ) *) * /

Math.Abs (required value) to find absolute values

Math.max (x, Y, z) The maximum value can be multi-valued (only two values before JS3).

Math.min (x, Y, Z ...) to find the minimum value  can be multi-valued (only two values before JS3).

Examples are as follows:

        //Math.Abs (required value) to find absolute valuesAlert (Math.Abs (100));// -Alert (Math.Abs (-100));// -Alert (Math.Abs (100-300));// $/*----------------------------------------------------------------*/        //Math.max (x, Y, z) The maximum value can be multi-valued (only two values before JS3). Alert (Math.max (100, 300, 200));// $Alert (Math.max (-100,-110));//-100Alert (Math.max (-100,-100));//-100/*---------------------------------------------------------*/                //math.min (x, Y, Z ...) to find the minimum value can be multi-valued (only two values before JS3). Alert (math.min (100, 300, 200)); Alert (Math.min (-100,-110));//-100Alert (math.min (-100,-100));//-100
