Tan()

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

inlinestaticconstexpr

Calculates tangent of an angle.

Uses multiple lookup tables with different granularities for optimal precision, especially near π/2 where tangent approaches infinity.

Implementation details:

• Dynamic table selection based on input range
• Higher precision near critical values
• Automatic angle wrapping and quadrant handling
• Handles positive and negative angles correctly

Table selection:

• tanTable1: [0, 0x3C00) - Base precision
• tanTable2: [0x3C00, 0x3F00) - Higher precision
• tanTable3: [0x3F00, 0x3FC0) - Even higher precision
• tanTable4: [0x3FC0, 0x3FF0) - Very high precision
• tanTable5: [0x3FF0, π/2) - Maximum precision

Parameters

angle

Input angle in turns

Returns

Tangent value in fixed-point format
