Using integer division in Python


Using integer division in Python

Hope that helps Python2.7 automatically uses the / operator as integer (whole number) division, which will always produce a whole number.
For example:
code :
Area = 1.0/2 * Base * Height # 1.0 is a float type, 1 is an integer type
Area = Base * Height * (1.0/2.0)
Base * Height * (0.5)
= 192 * 0.5
= 96
Base * Height * (1/2)
= Base * Height * (0) # since 1/2 rounds down to 0 in integer division
= 192 * 0
= 0
from __future__ import division
>>> from __future__ import division
>>> 1/2
0.5

this one helps. In Python 2, dividing 2 integers will always produce an integer. (In Python 3, you get "real" division)
You can rewrite your code as:
code :
[n/2.0 for n in range(100, 200)]
[float(n)/othervar for n in range(100, 200)]
from __future__ import division
Detecting integer division in python

Detecting integer division in python

To fix this issue I have to make the Python 2 to 3 jump. Integer division is the only thing that has me scared. Our test suite is OK, but not necessarily set up to scrutinize division. Is there some sort of wrapper or environment or hack from which I could run scripts that can detect when integer division is used? I mostly use Anaconda Python 2.7 on Windows. , You can run your code with the python 2 engine but with -3 switch:
code :
L:\>Python27_X64\python.exe -3 test.py
test.py:1: DeprecationWarning: classic int division
  i = 2/3
from __future__ import division
if False:
    i = 2/3
with open("toto.txt","wb") as f:
    f.write("foo")

Any of those help You can get the modulus by using / operator and remainder using % operator.
Check the following code:
code :
import ballerina/io;

public function main() {
    int i = 10;
    int j = 3;

    int x = i / j;
    int y = i % j;

    io:println("i / j = " + x.toString());
    io:println("i % j = " + y.toString());
}
i / j = 3
i % j = 1

I hope this helps you . From the documentation:

it should still fix some issue Python 2's / operator is either integer or floating point, depending on the types of the operands.
