Why does Python integer division yield a float instead of another integer?
Take a look at PEP-238: Changing the Division Operator
The // operator will be available to request floor division unambiguously.
Oops, immediately found 2//2. This will output an int rather than a float.
Behavior of Division Operator in Python 2.7 and Python 3
In Python 2.7: By default, division operator will return integer output.
To get the result in double multiple 1.0 to "dividend or divisor"
100/35 => 2 #(Expected is 2.857142857142857)(100*1.0)/35 => 2.857142857142857100/(35*1.0) => 2.857142857142857In Python 3
// => used for integer output/ => used for double output 100/35 => 2.857142857142857100//35 => 2100.//35 => 2.0 # floating-point result if divsor or dividend real
