Ah, I was trying to avoid calling getDoubleValue twice... Oh well, perhaps a method or a flag in a future release?? Thanks for your response.

There is no built-in function to do what you describe, but I can think
of a fairly simple way to accomplish what you want to do.  If you call
getDoubleValue() with no limits, it will trim the return only to the
largest and smallest allowable double values- you could use this return
value and compare it to the returned "trimmed" value- if they differed
you would know that one of your limits was used.

Does this help at all?
