Vector comparison operators are not available for doubles and uints
egorodet opened this issue · comments
operator ==, !=, <, <=, >, >= is not implemented for double1, double2, double3, double4 types and the implementation is commented out for uint1, uint2, uint3, uint4. Meanwhile these operators are properly implemented for floats and ints.
I'm trying to use vector types in my template wrapper class Point<T, N> which is used with floats, ints, uints and doubles and its is currently failing to compile for T=uint32_t and T=double because of this asymetry in underlying vector types implementation.
Would it be possible to implement these comparison operators for all vector types?
Ah yes, I have part of the code implemented locally. It shouldn't take long to add at all. Let me give it a quick go. I've always had issues determining what the == operator should return, either 0xffffffff or 1.0f for the result. Hlsl I think interprets it differently depending on what you do with it after, and will either treat it as a mask, treat it as a float with values 1.0 or 0.0, or treat is as a bool if inside a conditional. It would probably be possible to implement all this behavior through a boolN type, but for now I'll copy the same behavior that floatN has (float with 1.0 or 0.0).
