Can someone explain the following behavior?
In[48]:= $Version
Out[48]= HP9000 Series 700 2.2 (May 7, 1993)
In[49]:= Integrate[Exp[-(1-x)^2]/Sqrt[x],{x,0,Infinity}]
On::none: Message SeriesData::csa not found.
I 2 1 1
Out[49]= - Sqrt[-] BesselK[-, -]
2 E 4 2
In[50]:= N@%
Out[50]= 0.411862 I
In[51]:= NIntegrate[Exp[-(1-x)^2]/Sqrt[x],{x,0,Infinity}]
Out[51]= 1.97373
What is the meaning of csa?
Thanks for any help
