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
