I see. Then another possibility may be to make them part of the type by 
making them policies. The tradeoffs are obvious.

enum RoundingMode { ... }
enum Precision { ... }
enum Flags { ... }
struct BigFloatT(
     RoundingMode rm = ...,
     Precision pr = ...,
     uint flags = ...)
{
    ...
}

alias BigFloatT!(... common options ...) BigFloat;
