Using Liberty Basic to Calculate Pi with the Bailey-Borwein-Plouffe Algorythm
An interesting excersize (and useful in technical calculations) is the determination of pi to a high degree of precision. One of the simplest of the algorythms for the calculation of pi is the Bailey-Borwein-Plouffe Algorythm.
This code segment calculates the value of pi with accurate precision to 100 places. The more iterations performed, the deeper into the irrational number the precision may extend. With 100 places of precision the pi value may be considered accurate for any form of practical engineering or technical calculation.
'Program to calculate PI using the Bailey-Borwein-Plouffe Algorithm
Print "How many iterations to calculate (0-100)"input iterationspi = 0
if iterations > 100 then goto [end]for n = 0 to iterations
pi = pi + (4/((8*n) + 1) - 2/((8*n)+4) - 1/((8*n)+5) - 1/((8*n)+6))*(1/16)^n
next n
print using ("#.#############################################################", pi)
[end]input done
