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
