It was discovered in 1995 by Simon Plouffe and is named after the authors of the article in which it was published, David H. Bailey, Peter Borwein, and Plouffe. Before that, it had been published by Plouffe on his own site. The formula is The BBP formula gives rise to a spigot algorithm for computing the nth base-16 (hexadecimal) digi…

WebBasically a core fundamental principle is that whenever the last digit on the number goes past the base number, it overflows into the next slot. For example, in base 8, octal, when you add 1 to 7, it becomes 8 which you carry onto the next slot to get 10 which is in octal, but if you converted it back to base 10 then it would be 8.
