JavaScript Math Object


The Math object enables you to perform scientific assignments on numbers.


The Math Object

The Math object enables you to perform scientific tasks.

The Math object incorporates a few scientific methods.


One basic utilization of the Math object is to make an arbitrary number:

Example

Math.random();       /restores an arbitrary number

Math.min() and Math.max()

Math.min() and Math.max() can be utilized to locate the most minimal or most elevated an incentive in a rundown of arguments:

Example

Math.min(0, 150, 30, 20, - 8, - 200);     /returns - 200
Try it yourself »

Example

Math.max(0, 150, 30, 20, - 8, - 200);      /returns 150

Math.random()

Math.random() restores an irregular number between 0 (inclusive),  and 1 (exclusive):

Example

Math.random();              //restores an irregular number

Math.round()

Math.round() rounds a number to the closest integer:

Example

Math.round(4.7);            //returns 5
Math.round(4.4);            //returns 4
Try it Yourself »

Math.ceil()

Math.ceil() rounds a number up to the closest integer:

Example

Math.ceil(4.4);             /returns 5
Try it Yourself »

Math.floor()

Math.floor() rounds a number down to the closest integer:

Example

Math.floor(4.7);            //returns 4
Try it Yourself »

Math.floor() and Math.random() can be utilized together to restore an irregular number somewhere in the range of 0 and 10:

Example

Math.floor(Math.random() * 11);   //restores an irregular number somewhere in the range of 0 and 10

Math Constants

JavaScript gives 8 scientific constants that can be gotten to with the Math object:

Example

Math.E         /restores Euler's number
Math.PI        /returns PI
Math.SQRT2      /restores the square base of 2
Math.SQRT1_2    /restores the square base of 1/2
Math.LN2        /restores the common logarithm of 2
Math.LN10       /restores the common logarithm of 10
Math.LOG2E      /returns base 2 logarithm of E
Math.LOG10E     /returns base 10 logarithm of E
