Another trick you can do is taking the inverse.

1 div +0.0e0 gives the result INF
1 div -0.0e0 gives the result -INF

so for example 1 div $x > 0 is true for +0.0e0, but not -0.0e0

Hello,

how can I distinguish -0.0e0 from +0.0e0? The comparison operators (eq, lt, gt) are not supposed to to the job, and I am not sure if comparing string values is the right way. Any other suggestions?
I think treating them as strings is the only way...  Out of interest,
why do you need to distinguish them?
