Performers:

This is not performer question explicitly but since it is relates to my
performer app. and you guys/gals may have come across this before....

I need to verify whether or not position and orientation data is valid;
valid in the sense of being a valid number. Sometimes I receive data
(via ethernet packets) that is NaN, "not a numer" and I need to make sure
that it IS a valid floating point number before using it. Are there any
routines already available that check for valid floating point
representation?

Thanks much.
