The Math Object


This article explains about JavaScript MathObject


The JavaScript math object can be called without creating a new object for it.
The JavaScript Math object is used to compute common mathematical calculations. It includes several mathematical functions that can help in mathematical calculations.

Methods


Here are some important methods about Javascript Math Object

abs


abs(a) Returns absolute value of a.
ex: Math.abs(-2) results as 2

acos


acos(a) returns cosine of a in radians
ex: Math.acos(0) results as 1

asin


asin(a) returns cosine of a in radians
ex: Math.asin(0) results as 0

atan


acos(a) returns tan of a in radians
ex: Math.tan(0) results as 0

atan2


atan2(b,a)returns counterclockwise angle between x axis and point (b,a).

ceil


ceil(a) - rounds up the value of "a" to the next integer.
ex: ceil(3.14) results as 3

exp


exp(a) returns e to the power of a

floor


floor(x) rounds the passed value down to the next lowest integer.
ex: floor(3.74) results as 3

log


log(x) returns the natural logarithm (base E) of x

max


max(a,b) returns the larger value of a or b.
ex: Math.max(5,7) results as 7

min


min(a,b) returns the smaller value of a or b.
ex: Math.min(5,7) results as 5

pow


pow(a,b) returns the value of a to the power b
ex: Math.pow(5,2) results as 25

random


random(a,b) returns a random number between 0 and 1

round


round(a) returns the value of a to the nearest integer.
ex: Math.round(5.2) results as 5

sqrt


sqrt(a) returns the value of square root of a
ex: Math.sqrt(25) results as 5
