Angle conversion
Degrees, radians, gradians, turns and degrees-minutes-seconds.
Trigonometry
Degrees to radians
rad = deg × π/180→TrigonometryRadians to degrees
deg = rad × 180/π→TrigonometryDegrees to gradians
gon = deg × 10/9→TrigonometryDegrees to turns
turn = deg / 360→TrigonometryDMS to decimal degrees
D = d + m/60 + s/3600→TrigonometryNormalize angle
α₀ = ((α mod 360)+360) mod 360→
