FAQ

What is a gradian? A gradian (also grad or gon) divides a right angle into 100 units, giving 400 gradians per full circle. It is used in surveying.

When should I use radians? Radians are the natural unit for mathematics and physics — trigonometric functions in programming expect radians by default.
