In certain cases (big numbers) rounding to the floor may fail. That is why the trunc function is a perfect choice. 6. Precise Maths with decimal Module Python’s Standard Library goes one step forward. It grants us access to its another little pearl known as decimal module. Now the game is all about precision of calculations. When we use floating-point mathematical operations usually we do not think how computer represents the floats in its memory. 001000000000000000000000000000 It is just the way it is: the floats are represented in a binary format that involves a finite number of bits of their representation.

We import both functions but shorten their names to d and df, respectively. 60 You can skip this step if you would like to enforce the use of the full names or control the readability of your Python programs.
