Integer division (again)

Python Help
1

Hi all,

I realize that integer division has been discussed at length, but I haven’t been able to find a solution to my problem.
If I perform this most simple of commands in python:
print(int(3*42632001098429499/3))
I get

which I find extremely odd since 42632001098429499 is divisible by 3.
Anybody know how I can get a correct answer?
Thanks in advance!

This is performing floating point division when using / so you are limited by floating point precision. // would get you an integer value that matches what you expect.

I’m not even sure it is right to say // is integer division…but is floor division.

Since we know the value is exactly divisible by 3, it rounds to the nearest integer as expected.

Thanks all for your quick responses. It worked a treat. Although I officially don’t need floor division in this case it works well.
