That is to say result contains decimal part. see how we keep them straight with practice in Python. Calculating the floor of a number is a common mathematical function in Python. This is the default division operator behavior in Python 2.x as well as in today's dominant programming languages such as Java and C/C++. Then we can go a step further and use the Modulo Operator (percent symbol) % which gives you a remainder value or a zero. Modulo can help us determine if a number is positive or negative. If the numerator is N and the denominator D, then this equation N = D * ( N // D) + (N % D) is always satisfied. One can explicitly enforce true division or floor division using native functions in the operatormodule: from operator import truediv, floordivassert truediv(10, 8) == 1.25 # equivalent to `/` in Python 3assert floordiv(10, 8) == 1 # equivalent to `//`. Floor value is the value, which is the closest (must be less) or equal to the given number. So, for example, 5 / 2 is 2. So 7 % 3 is 5s equals To install Python 3 on Debian-based Linux distributions, click Back. divided by the integer 2. Next, M, multiplication is pretty straightforward, so two integer The Double Division operator in Python returns the floor value for both integer and floating-point arguments after division.
