Method

Purpose

Example

abs(x)

Returns only the value of x. Not sign either + or -.

var res=Math.abs(-1);

output :

1

acos(x)

Returns the trigonometry arccos value of x in

radians

var res=Math.acos(-1);

output:

3.14

asin(x)

Returns the trigonometry arcsin value of x in radians

var res= Math.asin(-1);

output:

-1.57

atan(x)

Returns the trigonometry arctan value of x in radians

var res= Math.atan(-1);

output:

-0.78

atan2(y, x)

Returns the arctangent value.  The value lies in between +pi and -pi

var res=Math.atan2(0, -0);

output:

3.14

ceil(x)

It rounds the value and return the whole integer.

var res=Math.ceil(98.94);

output:

99

cos(x)

Cosine of given input as output

var res=Math.cos(90);

output:

-0.44

exp(x)

Euler's constant to the power of given input as output

var res=Math.exp(1);

Output:

2.71

floor(x)

It truncates the decimal part  

var res=Math.floor(20.56);

Output:

20

log(x)

It displays natural logarithmic value of given input

var res=Math.log(10);

output:

2.30

max(x, y, z, ..., n)

It displays the maximum value from the given inputs

var res=max(6,8,10);

output:

10

min(x, y, z, ..., n)

It displays the minimum value from the given inputs

var res=min(6,8,10);

output:

6
