I'm testing big integers in Python; they are implemented as an object with sign and an array of digits. It's, basically, to describe Karatsuba Multiplication, and, for those big integers, I need the same behaviour like oridinary numbers with integer division by 10
, and, there is a problem:
Why, in Python, -22 // 10 = -3
?
Dividing by //
is a floor division.
Floor division goes to the lower number without a .
22 // 10
results to the next lower value 2
.
-22 // 10
results to the next lower value -3
To do a normal division you can run -22 / 10 This results into
- 2.2
