Decimal is based on a floating point model which was designed with people in mind and necessarily has a paramount guiding principle computers must provide an arithmetic that works in the same way as the arithmetic that people learn at school excerpt. X this is a numeric expression. Import math math floor 3 1415 the problem with the first approach is that it return a float namely 3 0 the second approach feels clumsy and too long.
