Pi is an irRATIOnal number, meaning that it is not equal to the ratio of any
integers ("whole numbers"). Hence, 22/7 is ONLY an approximation. The
built-in value for pi in R is also just an approximation (pi has no terminal
digit on the right of the decimal point so any finite number of digits will
just be an approximation). Yet, the built-in value for pi in R is a more
precise approximation, which is usually preferred...

3.141593. So which value of pi should be considered?
