Angle API
Convert and normalize plane angles. The convert endpoint moves a value between degrees, radians, gradians (gons), turns/revolutions, arcminutes, arcseconds, milliradians and DMS (degrees-minutes-seconds) — parse a DMS string like 12°34'56" or format a decimal angle as DMS. The normalize endpoint wraps any angle into the 0–360° or the −180–180° range. Perfect for graphics and game maths, CAD and surveying, robotics, astronomy and navigation headings. This covers plane angles specifically — a category general unit converters leave out. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from general unit conversion and from geographic-coordinate conversion.
