Saturated arithmetics

[ronaldvanmanen]

Dear Robert,

I've been using the Boost Safe Numerics library to implement safe color arithmetic. However, I've come to the conclusion that in some cases when adding two colors, for example, the operation should not overflow or underflow, but saturate instead. So I was wondering if this is something that can be done with the Boost Safe Numberics library today. Or that this may be feature that would be suitable to add to the Boost Safe Numerics library.

With kind regards,
