JavaScript – Objects – Math Object

The Math object’s method allow the programmer to perform mathematical calculations.
An object’s method’s are called by writing the name of the object followed by a dot operator and the name of the method.
Following the method name is the argument/s to the method.

Some math objects:

Method	Description
abs(x)	absolute value of x
ceil(x)	rounds x to the smallest integer not less than x
cos(x)	trigonometric cosine of x (x in radians)
exp(x)	exponential method of x^e
floor(x)	rounds x to the largest integer not greater than x
log(x)	natural logarithm of x (base e)
max(x,y)	larger value of x and y
min(x,y)	smaller value of x and y
pow(x,y)	x raised to the power of y (x^y)
round(x)	rounds x to the closest integer
sin(x)	trigonometric sine of x (x in radians)
sqrt(x)	square root of x
tan(x)	trigonometric tangent of x (x in radians).

The Math object also defines mathematical constants.
By convention all constants are written in all uppercase letters.

Constant	Value
Math.E	Euler’s constant
Math.LN2	Natural logarithm of 2
Math.LN10	Natural logarithm of 10
Math.LOG2E	Base 2 of logarithm of Euler’s constant
Math.LOG10E	Base 10 of logarithm of Euler’s constant
Math.PI	PI – the ratio of a circle’s circumference to its diameter.
Math.SQRT1_2	Square root of 0.5
Math.SQRT2	Square root of 2.0
