Why print(-5//2) give - 3 not - 2 ?

Answer 1

Python takes a very literal view of its definition of floor division. Floor division returns the nearest integer that is equal to or less than the division result.

The division result would be
-5/2 = -2.5

Since -2.5 is not an integer, Python looks for the next lower integer, and that value is -3.

Answer 2

It is always the next left integer on the number line.

Answer 3

# operator will divide the first argument by the second and round the result down to the nearest whole number making it equivalent to the math.floor() function#

Answer 4

#Simple logic
#points to Remeber : 2>1>0> -1>-2>-3>
#Floor division // gives integer value .
a = -7//2
print(a)
#output : -4
