Integer division in Python 2 and Python 3 Question: How can I divide two numbers in Python 2.7 and get the result with decimals? I don’t get it why there is difference: in Python 3: >>> 20/15 1.3333333333333333 in Python 2: >>> 20/15 1 Isn’t this a modulo actually? Asked By: Erzsebet || Source Answers: …
In Python, what is a good way to round towards zero in integer division? Question: 1/2 gives 0 as it should. However, -1/2 gives -1 , but I want it to round towards 0 (i.e. I want -1/2 to be 0), regardless of whether it’s positive or negative. What is the best way to do …
Python 3 integer division Question: In Python 3 vs Python 2.6, I’ve noticed that I can divide two integers and get a float. How do you get the Python 2.6 behaviour back? Is there a different method to get int/int = int? Asked By: Megatron || Source Answers: Try this: a = 1 b = 2 …
Python: Remove division decimal Question: I have made a program that divides numbers and then returns the number, But the thing is that when it returns the number it has a decimal like this: 2.0 But I want it to give me: 2 so is there anyway I can do this? Asked By: Dan Alexander …
python: getting around division by zero Question: I have a big data set of floating point numbers. I iterate through them and evaluate np.log(x) for each of them. I get RuntimeWarning: divide by zero encountered in log I would like to get around this and return 0 if this error occurs. I am thinking of …
Negative integer division surprising result Question: In my application I encountered the following and was surprised by the results: 8/-7=-2 (both integers). What does this mean? Asked By: Vivek S || Source Answers: For the actual values, i.e. 8.0/(-7.0), the result is roughly -1.143. Your result using integer division is being rounded down toward the …
Why does integer division yield a float instead of another integer? Question: Consider this division in Python 3: >>> 2/2 1.0 Is this intended? I strongly remember earlier versions returning int/int = int. What should I do? Is there a new division operator or must I always cast? In 2.x, the behaviour was indeed reversed; …
How can I force division to be floating point? Division keeps rounding down to 0? Question: 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 …
