Adam,
I think this has already been discussed a lot in this list,
but it's never too much: It's not a good practice to "stuff" a
interrupt handler with "complicated" code, e.g. floating point
calculations. As a good thumb rule: If your program design re-
quires floating point at the handler level, there is something
wrong with your design or with you. :-)
In *your* case, I believe it's the design. ;-)
Take care.
