Cos()

static constexpr Fxp SRL::Math::Trigonometry::Cos ( const Angle & angle )

inlinestaticconstexpr

Calculates cosine of an angle.

Implemented as sin(x + π/2) to reuse the sine table. The input angle is automatically wrapped to [0, 2π].

Implementation details:

• Reuses sine table for memory efficiency
• Phase shift by π/2 for cosine values
• Same precision as sine function

Parameters

angle

Input angle in turns

Returns

Cosine value in fixed-point format [-1, 1]
