Sqrt()

template<Precision P = Precision::Default>

Fxp SRL::Math::Types::Fxp::Sqrt ( ) const

inlineconstexpr

Calculate square root with configurable precision.

Template Parameters

P	Precision level for calculation

Returns

Square root with specified precision

Provides two precision levels with different performance and accuracy trade-offs:

• Standard: Full precision calculation using the digit-by-digit algorithm
• Fast: Approximation with varying error rates: • Maximum error of ~42% observed at very small values (~0.000046) • Error decreases as values increase, with most values below 0.0015 having errors between 6-20% • For values above 0.0015, maximum error stabilizes around 6.3%

Choose the appropriate precision based on your requirements:

• Standard: Use for critical calculations where accuracy is essential
• Fast: Best for non-critical real-time effects where performance is paramount

Note

Turbo precision mode defaults to Fast for this function.
