I have two integer values a and b, but I need their ratio in floating point. I know that a < b and I want to calculate a / b, so if I use integer division I’ll always get 0 with a remainder of a.
It’s well known that comparing floats for equality is a little fiddly due to rounding and precision issues.
Is there a way to step between 0 and 1 by 0.1?
Just for fun and because it was really easy, I’ve written a short program to generate Grafting numbers, but because of floating point precision issues it’s not finding some of the larger examples.
Here’s my code:
I have a number of strings similar to Current Level: 13.4 db. and I would like to extract just the floating point number. I say floating and not decimal as it’s sometimes whole. Can RegEx do this or is there a better way? Answers: Thank you for visiting the Q&A section on Magenaut. Please note … Read more
How can I format a float so that it doesn’t contain trailing zeros? In other words, I want the resulting string to be as short as possible.
I have a function taking float arguments (generally integers or decimals with one significant digit), and I need to output the values in a string with two decimal places (5 → 5.00, 5.5 → 5.50, etc). How can I do this in Python?
I have a Decimal('3.9') as part of an object, and wish to encode this to a JSON string which should look like {'x': 3.9}. I don’t care about precision on the client side, so a float is fine.
How can one modify the format for the output from a groupby operation in pandas that produces scientific notation for very large numbers?
