This article mainly explains "what are the operation methods of JavaScript Math function". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the operation methods of JavaScript Math function".

Ceil,floor,sin,cos operation of JavaScript Math function

Math.ceil ()

The return value of Math.ceil (x) is the nearest integer rounded on x:

Example

Math.ceil (6.4); / / returns 7

Math.floor ()

The return value of Math.floor (x) is the nearest integer rounded under x:

Example

Math.floor (2.7); / / returns 2

Math.sin ()

Math.sin (x) returns the sine of the angle x in radians (a value between-1 and 1).

If you want to use angles instead of radians, you need to convert angles to radians:

Angle in radians = Angle in degrees x PI / 180.

Example

Math.sin (90 * Math.PI / 180); / / returns 1 (90-degree sine)

Math.cos ()

Math.cos (x) returns the cosine of the angle x in radians (a value between-1 and 1).

If you want to use angles instead of radians, you need to convert angles to radians:

Angle in radians = Angle in degrees x PI / 180.

Example

Math.cos (0 * Math.PI / 180); / / returns 1 (cosine of 0 degrees)
