We have not looked into a safe version, but we follow the normal IEEE 754 convention where overflow, underflow, div by 0, etc. result in +/-INF and NAN. I think (but have no tried) that the decimal types fulfill all of the Safe Numerics conceptual requirements for Numeric<T>, and then could be used with Safe Numerics if that safety is desired.
