Impletemt true division and floor division in coco.
When dividing an integer by another integer in python 3 the division operation x y represents a true division uses truediv method and produces a floating point result.
Floor division the division of operands where the result is the quotient in which the digits after the decimal point are removed.
So for example 5 2 is 2.
For python 2 x dividing two integers or longs uses integer division also known as floor division applying the floor function after division.
The integer division value is added with the checking value to get the ceiling value.
But if one of the operands is negative the result is floored i e rounded away from zero towards negative infinity.
Division and type conversion.
Given below is the illustration of the above approach.
The division and floor division operators yield the quotient of their arguments.
Using to do division this way is deprecated.
Division of integers yields a float while floor division of integers results in an integer.
From the ansi c draft 3 3 5.
The standard division symbol operates differently in python 3 and python 2 when applied to integers.
2 3 first output is fine but the second one may be surprising if we are coming java c world.
In python 3 is float division.
The numeric arguments are first converted to a common type.
In python 2 is integer division assuming int inputs in both 2 and 3 is integer division to get float division in python 2 requires either of the operands be a float either as 20.
The result is that of mathematical division with the floor function applied to the result.
If you want floor division use available in python 2 2 and later.
A b returns the integer division value and a b 0 is a checking condition which returns 1 if we have any remainder left after the division of a b else it returns 0.
Dirkgently gives an excellent description of integer division in c99 but you should also know that in c89 integer division with a negative operand has an implementation defined direction.
Meanwhile the same operation in python 2 represents a classic division that rounds the result down.
Floor division and modulo are linked by the following identity x x y y x y which is why modulo also yields unexpected results for negative numbers not just floor division.
