Piphilology: Difference between revisions

This second one gives the value of π as 3.141592653, although 3.141592654 is a more correct figure. Indeed, many published piems use [[truncation]] instead of true [[rounding]], thereby producing a less accurate result when the first omitted digit is greater than or equal to 5. It should however be noted that it is advantageous to use truncation in memorising if the individual intends to study more places later on.
