FastSqrt()

static constexpr uint32_t SRL::Math::Integer::FastSqrt ( uint32_t src )

inlinestaticconstexpr

Fast integer square root approximation with ~6% error.

Binary search approximation supporting full uint32_t range. Maximum 15 iterations after initial right shift by 2. Ideal for games where integer precision is sufficient and performance matters more than perfect accuracy.

Parameters

src	The 32-bit integer value.

Returns

Approximate square root as whole number.
