Concept
space::irbem::SoundPrecision
cheatah-space v0.1.0-alpha — Biome Standard 0.6.5-alpha
A precision policy that may actually be used: a Precision whose accumulator is double.
The integrand type is free — that choice is bounded by unit_roundoff, which does not grow with the size of the problem. The accumulator type is not free, because naive_sum_bound does grow with it, and at the ~10³ terms of one field-line quadrature an fp32 accumulator lands on the discretization floor itself (ERROR_BUDGET §3). Anything constrained on this concept cannot be instantiated with such a policy.
