Constant traits not working for integer types #226

Open Speierers opened 6 months ago

Speierers commented 6 months ago

The constant traits in const.py and array_constants.h do not handle integer types properly as they assume floating-point types.

For the traits specific to floats (e.g. dr::Pi, dr::Epsilon) we should probably add a static assert, and other traits (e.g. dr::Smallest, dr::Largest, ...) should be fixed.

If I find the time, I will try to open a PR to fix those issues.

Hi @Speierers,

Just in case you're referring to the non-nanobind version, before opening a PR, check out the upcoming version, which I believe is implemented differently (don't know how it handles integer types though): https://github.com/mitsuba-renderer/drjit/blob/nanobind_v2/include/drjit/array_constants.h

Good point @merlinND 👍 although I think the issue is still there in the nanobind version.
