Inf in query / eval

[amelio-vazquez-reina]

In df.eval() or df.query(), is there any way to run comparisons against np.Inf?

When I do:

temp_df.eval('my_col < Inf') or
temp_df.eval('my_col < np.Inf') or

I get UndefinedVariableError

Just needs to be added to the global constants.

Thanks @cpcloud What do you mean? Is this something specific to numexpr or Pandas?

I can do this in an hour or so if you look in computation/scope.py and want to take a crack at it before then please do.

@ribonoous sorry about the above explanation; I didn't mean to be so cryptic. The reason this fails is actually because the "builtins" to eval are not looked up correctly (which is actually a bug). If you can't wait for the fix to be merged just slap an @ on the front of inf and as long as it's defined in the scope where you call eval / query you're golden.

Great. That makes sense. Thanks @cpcloud
