Re: How to define specific value for BAD?

[Jeremy S Pal <jpal@xxxxxxx>]

  Hi Daniel -

It seems to me that the 'bad=0' qualifier should work.  Given
that it doesn not, an if statement might work in the following
manner:

  let v2 = if v1 lt 0.0001 or v1 gt -0.0001 then 1/0 else v1

I hope this helps.
