Hello everybody. I've seen this question arise sometimes on the list, but don't know if something has "happened" yet or not. I mean, any solution feasible to use more or less right out of the box? I'm just a hardware engineer, so it would be difficult for me to create my own class for this, since my knowledge of python/numpy is very limited, and, just don't have the time/knowledge to be more than a simple user of the language, not a developer. I have just come across this: http://www.dilloneng.com/documents/downloads/demodel/ but haven't used it yet. I'll give it a try and see how it works and come back to the list to report somehow. But, is there any "official" plans for this within the numpy developers? Is there any code around that may be used? I just need to test my code with fixed point arithmetic (I'm modelling hardware....) Thanks for the good work to all the Python/Numpy developers (and all the projects related, matplotlib and so on....) and for the possiblity of freeing from matlab!!! I'm determined to do research with as many free software design tools as possible....though this fixed-point arithmetic issue is still a chain! Regards!
