What's the result of

float4 v = (float4)(-2.0f,1.0f,-3.0f,4.0);

XXXX res = (v<0.0f)

pls?

an int4 like (1,0,1,0) ???

int4 like (-1, 0, -1, 0)

It's defined in the spec section 6.3.d, for scalar type it's int, 1 for true and 0 for false like C.

Yes, it differs for vector and scalar types, I hate it too.

Thanks, I didn't see that.

What I hate are statements in the official documentation without examples

I donot think we should expect these examples from spec doc. If spec start adding examples, it becomes 3000 pages instead of 300 pages.
