template<typename T = void>

static constexpr Angle SRL::Math::Trigonometry::Acos ( const Fxp & value )

inlinestaticconstexpr

Calculates arccosine (inverse cosine) of a value.

This function computes the angle whose cosine equals the input value. The input value must be in the range [-1, 1].

Parameters

value

Input value in range [-1, 1]

Returns

Angle in range [0, 0.5] turns (0° to 180°)
