... if you sure that the formulation of your loop is correct you could
try using double precision numbers. This will just allow value to become
even closer to 0 than it was already:

IDL> print, 1e-50 / 17000
0.00000
% Program caused arithmetic error: Floating underflow
IDL> print, 1d-50 / 17000d
5.8823529e-55
