Hi, Have you read the implementation of mp_binary_op in runtime.c -- in this case the relevant detail is that it calls mp_obj_equal_not_equal. Not recently, so if it has changed recently, then I am not up to date. It goes through a bunch of the steps, to finally call the type's binary_op. Important...

Hi all, Before raising an issue on github, I wanted to ask, whether I try to do something note quite legal. I would like to clean up the implementation of the == , and != binary operators in ulab , and I don't get what I expect. Namely, the following code does what it is supposed to import ulab a = ...

Jim,


Thanks for the comments! I wasn't aware of the difference between binary and comparison operators; at the moment, I handle everything in a single switch in binary_op, but obviously that is not the way to go. I will try to incorporate your suggestions.

Cheers,
Zoltán

Hi all, in numpy , the following is valid a = array([1, 2, 3, 4]) a < 2 2 > a Both expressions mean the same, the difference is in, whether the array stands on the right or left hand side of the less than/more than operator. In micropython , operand ordering is handled via the MP_BINARY_OP_REVERSE_ ...

Jim, as requested, I have modified the makefiles, and issued a PR: https://github.com/micropython/micropython/pull/5789

But yes, if you did need to set a linker flag from your C module makefile, then if that's not currently possible then it would be worth sending a PR to make it possible. I will take a look later.

OK, I'll update the makefiles, and send a PR.

I have tried to add the linker flag in the Makefile, but that doesn't help at all. Can you explain what you mean by that... I added -lm to the linker flags. you should just need to add roundf.c to SRC_LIBM. (It seems to work for me). That solved it, thanks! However, I haven't yet found a way of app...

Hi all, I have attempted to add the around function to ulab , and to that end, I call math's round as MICROPY_FLOAT_C_FUN(round) https://github.com/v923z/micropython-ulab/blob/master/code/vectorise.c#L156 . This works on the unix port, but I can't compile for the pyboard, and get a linker error LINK...

Talking about https://github.com/stinos/micropython-wrap/blob/master/classwrapper.h#L372 bascially. With 'we' I meant 'me and colleagues' but actually I wrote all of it so on second thought: yes would be less confusing to just say 'I' :D Sorry, I wasn't nit-picking, I was simply curious. This wrapp...

That overrides the locals dictionary, so nothing defined in the locals will be available as a class method. Yup, forgot we use a custom attr function which does all of that, i.e. first lookup locals dict then property getters etc Just curious: who is "we"? You did exactly what Jim's suggested earli...
