ASMPI  is  a program I made back in December '92 to calculate PI
in 100% assembly.  The program itself is still a little rough around
the edges, and the  source  code  could use some more documentation,
but  it's  still  a neat program to fool around with on a rainy day.

    ASMPI is extremely fast!  On my very slow 286/10 (a  Tandy  1000
RLX,  those  bastards  ripped  me  off  big time!), it can calculate
36,000 digits of PI in 21 minutes!  That's fast!  I've optimized the
time  critical  routines  as  much  as  I  could  by  unrolling  the
calculation loops  (to  avoid  jumps,  refer  to  any Michael Abrash
column) and by tracking  how  large  each  binary number is to avoid
needless multiplies and divides.  (Thanks to  Victor  Yui  for  this
suggestion.)

    I've  verified  the output of ASMPI to 10,000 digits with a text
file I found on a  local  BBS.   The  EXE  file I included with this
archive was assembled for 10,000 digits -  if  you  want  any  more,
you'll have to reassemble ASMPI.ASM with TASM.

    We'll, have fun!
