Math helper functions.

Traits

  • FastInvSqrt
    Implement the fast approximate computation of ‘1/sqrt(x)’ for a type.

Functions

  • fast_invsqrt_32
    Fast approximate computation of 1/sqrt(x). The error should be below 0.2%.
  • fast_invsqrt_64
    Fast approximate computation of 1/sqrt(x). The error should be below 0.2%.
  • int_sqrt_floor
    Compute square root of integers using Newtons method. Returns the biggest integer which is smaller or equal to the actual square root of n. Similar to (i as f64).sqrt().floor() as T but without type conversions.
