I don’t understand your problem well enough to know, if you can (or want to) use this here, but you might be able to tap into that C performance with the radix conversion formatting of printf.
The problem is printing big binary to decimal. That’s not a easy problem because 10 is not a power 2. If we live in a base-hex world, this would be very easy to solve in O(n).
Also, I can’t access that as G’MIC is a language that can’t really communicate with other language as it’s not meant to share memory.
This. I’m coding to contribute to a open-source software with very small amount of coders, and with a non-mainstream Domain-Specific Language. A lot of the code I did before has been proven to work from times to time, but they all could benefit from better outputs and better GUI. So, I end up reengineering the entire and that’ll take a really long time, however, I do a lot of tests to ensure it works.
