WebAs a workaround, it is possible to modify boost.rational so that it doesn't instantiate std::numeric_limits for array types, and perhaps for function types (and this is what boost folks should probably do). Why not instantiate only for arithmetic types? Converting anything but an arithmetic type to a rational doesn't seem to make sense. WebOct 25, 2024 · Rounding is inherently lossy.
