John,

Have you tried using Chop?

a + (0. + 0.i) // Chop
a

Hi Group,

When solving an ODE i get the correct result, but a lot of (0.+0.i) 
expressions are included. How can i tell Mathematica(V5) to discard 
these "nearly" zero's. Guess it is something about precision or accuracy.

Best regards (Mathematica-newbee)
John
