Methods

Static fromRadian

fromRadian(rad: number): number

- Defined in Stopwatch.Degree.ts:90
description
Change the unit of angle from radian to degree.

example
```
// 90
const degree = Stopwatch.Degree.fromRadian( Math.PI / 2 );
```
Parameters
- rad: number
  
  angle to change ( radian )
Returns number
changed angle ( degree )

Static normalize

normalize(deg: number): number

- Defined in Stopwatch.Degree.ts:20
description
Normalize the angle. ( 0 <= angle < 360 )

example
```
// 9
const degree = Stopwatch.Degree.normalize( 369 );
```
Parameters
- deg: number
  
  angle to normalize
Returns number
normalized angle

Static toRadian

toRadian(deg: number): number

- Defined in Stopwatch.Degree.ts:71
description

example
```
// Math.PI
const radian = Stopwatch.Degree.toRadian( 180 );
```
Parameters
- deg: number
  
  angle to change ( degree )
Returns number
changed angle ( radian )
