Values of Pi with Greater Precision

More Precise Values of Pi

math.Pi

The math libraries of many languages define Pi as a Double, a 64-bit floating point value: 3.141592653589793

What do you do if you need greater precision? Well in Scala (and other JVM languages) you can use BigDecimal, see One Million Digits of Pi

Stern-Brocot Sequence

Stern-Brocot Sequence

The S-B Sequence has the curious ability, when taking adjacent pairs, to be able to represent all possible fractions without repeating any of them. The sequence is similar to a Fibonacci Sequence but with 2 members appended as it progresses rather than 1:

1, 1, 2, 1, 3, 2, 3, 1, 4, 3, 5, 2, 5, 3, 4
^  ^  
|  |            Append two members to the sequence, first:

| +---- b

A drop-in block of html with embedded script and styles -- ugly but does the job.
