I'm trying to model a magnetic field with maple.
In order to do that, I compute a (huge) sum and integrals of real and posive numbers.
The problem is that for some points, when I compute the norm of this field I get an imaginary number with a very small imaginary part (egs -2, 27293.1844462+1.42305652280*10^(-84)*I ).
How can I get rid of it?
thx in advance
