Frequently Asked Questions
Why do programming languages use radians instead of degrees?
Most math libraries (including JavaScript's Math object) expect trigonometric functions in radians, since radians simplify calculus and geometry formulas.
What is a gradian?
A gradian (also called a gon) divides a right angle into 100 units instead of 90 degrees, and is occasionally used in surveying and some European countries.
How precise is the conversion?
Results are shown to 8 decimal places, using JavaScript's built-in floating-point precision.
