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
