Formatting floating point numbers to a specific number of significant digits in Python
For more information see my blog post on this topic.
Hi Randle, I like this and I'm confused why there isn't something already more developed for this.
I think it would be nice if there were more formatting options for this library. More specifically it would be nice if converting to scientific notation was an option.
When inputting to_precision(132,2), I would expect it to return '130', but it actually gives '1.3e+2'. To my knowledge, both have the valid amount of significant figures, and the first one is easier to read. We might want to add a trailing zeros check.
I tried it on python 2.7 and 3.4 and got the same result.
Thanks so much for sharing this. I really like the code.
