> f[a_] := 2 I Pi Sin[a]/a Hi. I don't have a solution to the question, but this may work better at 0. g[a_]:=2 I Pi Sinc[a] g[0.] 0.\[VeryThinSpace]+6.283 I vs. Power::infy: f[0.] Power::infy: Infinite expression 1/0. encountered. = = = = = = = = = = HTH : >) Dana DeLouis Chop does not seem to work properly in Mathematica 8.0.1: f[a_] := 2 I Pi Sin[a]/a In[2]:= f[1.] Out[2]= 0. + 5.287118128162912*I In[3]:= Chop[%] Out[3]= 0. + 5.287118128162912*I This is with In[4]:= $Version Out[4]= 8.0 for Mac OS X x86 (64-bit) (February 23, 2011) Mathematica 7.01 returns 5.287118128162912*I as expected. Can anyone confirm it? At the moment I can't see any simple work around... Andrzej Kozlowski
