Math.RAD_PER_DEG and Math.DEG_PER_RAD constants have invalid names in the current spec:
Math.RAD_PER_DEG is equal to 180 / PI, but must be equal PI / 180, because this constant means radians in one degree. Also Math.radians(degrees) must be computed as
- 2. Let radians be (degrees × Math.DEG_PER_RAD).
+ 2. Let radians be (degrees × Math.RAD_PER_DEG).
Accordingly Math.DEG_PER_RAD must be equal 180 / PI, because it means number of degrees in one radian, and Math.degrees(radians) must be computed as:
- 2. Let degrees be (radians × Math.RAD_PER_DEG).
+ 2. Let degrees be (radians × Math.DEG_PER_RAD).
