Accuracy and rounding
Radians are common in math and code; degrees are common in maps, tools, and everyday angle measurements.
Degrees, radians, gradians, and turns are fixed ways to express the same rotation.
For display, one or two decimals is usually enough. For code, CAD, or trigonometry, keep more precision.
