JavaScript Math Object

Unlike other objects, the Math object has no constructor.

All methods and properties can be used without creating a Math object first.

The syntax for any Math property is : Math.property.

JavaScript provides 8 mathematical constants that can be accessed as Math properties:

• Math.E

• Math.PI

• Math.SQRT2

• Math.SQRT1_2

• Math.LN2

• Math.LN10

• Math.LOG2E

• Math.LOG10E

Math Methods

The syntax for Math any methods is : Math.method(number)

Math.ceil(x) -> Math.ceil(x) returns the value of x rounded up to its nearest integer

Math.round(x) -> Math.round(x) returns the nearest integer

example : Math.ceil(4.9);

Math.floor(x) -> Math.floor(x) returns the value of x rounded down to its nearest integer

example : Math.floor(4.9);

Math.trunc(x) -> Math.trunc(x) returns the integer part of x
