This it the third version of a program for computing Pi up to 2150
places.

The first version was written in Turbo Pascal 3. The second was also
in Turbo Pascal, but with all the math procedures converted to inline
for maximum program executing speed.

This version is rewritten to allow compilation with Turbo Pascal 5 and
up.

The inline code was scrapped for version 3. The sacrifice in speed is
not a problem, because it improvement in today's computers overshadows
the processing efficiency loss.

Here are my results using a 33MHz 386.

Pi v2                               Pi v3
100  places =  0.1 sec              100  places =   0.3 sec
1000 places = 11   sec              1000 places =  32   sec
2135 places = 48   sec              2135 places = 150   sec
