JavaScript | Math Object

The Math object is used to perform mathematical operations on numbers. There are many math object properties which are listed below:

Property	Description
Math.E	Euler’s number
Math.PI	PI
Math.SQRT2	The square root of 2
Math.SQRT1_2	The square root of 1/2
Math.LN2	The natural logarithm of 2
Math.LN10	The natural logarithm of 10
Math.LOG2E	Base 2 logarithm of E
Math.LOG10E	Base 10 logarithm of E

Math objects: There are many math objects exists in JavaScript which are listed below:

Property	Description
abs(x)	Absolute value of x
acos(x)	Arccosine of x, in radian
asin(x)	Arcsine of x, in radian
atan(x)	Arctangent of x, a numeric value between -PI/2 and PI/2 radian
atan2(y, x)	Arctangent of the quotient of its arguments
ceil(x)	Value of x rounded up to the nearest integer
cos(x)	Cosine of x (x in radians)
exp()	Value of E^x
floor()	Value of x rounded below to the nearest integer
log()	Natural logarithm (base E) of x
max(a, b, …)	Highest value
min(a, b, …)	Lowest value
pow(x, y)	Value of x to power of y
random()	Random number between 0 and 1
round(x)	Value of x rounded to the nearest integer
sin(x)	Sine of x (x in radians)
sqrt(x)	Square root of x
tan(x)	Tangent of angle

Example 1: This example use math object properties to return their values.
