Hi,
I'd realy appreciate someone pointing out why I'm an idiot.

I'm trying to set some values of an image to NaN so that they are not
included in further calculations but I can't seem to do it!!!

eg:
a = indgen(10)
lt5 = where(a LT 5)
a(lt5) = !VALUES.F_NAN
%Program caused arithmetic error: Floating illegal operand
print, a
0 0 0 0 0 5 6 7 8 9

Cheers
Matt
