Many thanks to all - this is very helpful.
Dan, I'll explore some of these other options you mention. In this new
PR, is it the case that by switching to using theLLVM dialect these
operators will automatically be recognised? I suppose if this is the
case then explicitly adding the operator might not strictly be
necessary...
Yes, with the LLVM dialect, if your input bands are of integer type and
you specify an output integer type, bitwise and will be done in the
integer domain.
Also, I appreciate the clarification that values are always
converted to float during the arithmetic, I agree, Javier, that in
this case a bitwise operation is a bit strange...
When using muparser, yes they are converted to double, since its
"official" API only exposes that data type. But if the absolute value of
integer values is below 1 << 53, they are perfectly represented as a
double, so this is generally not much of an issue.
