# JavaScript Math Object

---

● Math.round()

 Math.round(x) returns the value of x rounded to its nearest integer.

● Math.pow()

 Math.pow(x, y) returns the value of x to the power of y.

● Math.sqrt()

 Math.sqrt(x) returns the square root of x.

● Math.abs()

 Math.abs(x) returns the absolute (positive) value of x.

● Math.ceil()

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

● Math.floor()

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

● Math.sin()

 Math.sin(x) returns the sine ( -1 <= value <=1 ) of the angle x (radians).
If I want to use degrees instead of radians, I have to convert degrees to radians.
<Angle in radians = Angle in degrees * PI/180>

● Math.cos()

 Math.cos(x) returns the cosine of the angle x (radians).

● Math.min() and Math.max()

 Math.min() and Math.max() can be used to find the lowest or highest value in a list of arguments.

● Math.random()

 Math.random() returns a random number between 0, and 1.

● Math.Properties ( Constants )

 JavaScript provides 8 mathematical constants that can be accessed with the Math Object.

● Math.Constructor

 Unlike other global objects, the Math Object has no constructor. Methods and properties are static. All methods and properties can be used without creating a Math object first.
