An absolute difference would be the absolute value of the difference between 2 numbers. Suppose I have 2 int variables (x and y) and I would like to find the absolute difference. An easy solution w...

Numpy provides both np.absolute and the alias np.abs defined via
from .numeric import absolute as abs
which seems to be in obvious violation of the zen of python:
There should be one-- and pr...

This was my try. For example
df = pd.DataFrame({'a':[5,0,1,np.nan], 'b':[np.nan,1,4,3], 'c':[-3,-2,0,0]})

Filters out well the NaN values but it gets 0 or n...

This code:
System.out.println(Math.abs(Integer.MIN_VALUE));
Returns -2147483648
Should it not return the absolute value as 2147483648 ?

How does this work?
The idea is to make abs(x) use bitwise operators for integers (assuming 32 bit words):
y = x >> 31
(x + y) ^ y // This gives abs(x) (is ^ XOR)?
