The following uses the arbitrary integer long of python to compute Pi. Can some one help getting this to use&nbsp;the Numeric package in float arbitrary precision.?&nbsp;
 def piasn(n): &nbsp;&nbsp;&nbsp;&nbsp; n1=n*7/2+5 &nbsp;&nbsp;&nbsp;&nbsp; n2=n/2 + 5 &nbsp;&nbsp;&nbsp;&nbsp; import time &nbsp;&nbsp;&nbsp;&nbsp; t1=time.time() &nbsp;&nbsp;&nbsp;&nbsp; m=n+5 &nbsp;&nbsp;&nbsp;&nbsp; p,x,d = 3*10**m,3*10**m,1 &nbsp;&nbsp;&nbsp;&nbsp; t1=time.time() &nbsp;&nbsp;&nbsp;&nbsp; while d &lt;= n1: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; x=x*d/(d+1) &gt;&gt; 2 #&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; x=x*d/(d+1)/4 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; p=p+x/(d+2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; d += 2 &nbsp;&nbsp;&nbsp;&nbsp; t2=time.time() &nbsp;&nbsp;&nbsp;&nbsp; print "Pi = ",p &nbsp;&nbsp;&nbsp;&nbsp; print "sec to calc",t2-t1
