Use Chop[] (see help browser for details) In[]:= Chop[0. + 0. I] Out[]= 0 In[]:= Chop[{1. + 0.7*I, 0. + 0.*I}] Out[]= {1.\[InvisibleSpace] + 0.7 \[ImaginaryI], 0} Regards, Mihajlo Vanevic www.mihajlo.greatnow.com 2003-11-19 ************************************************************** * At 2003-11-19, 04:59:00 * John Jansen, Johh at Jansen.net wrote: ************************************************************** >Hi Group, > >When solving an ODE i get the correct result, but a lot of (0.+0.i) >expressions are included.
