Floating point calculations on 16 uC

Hi,

I'm doing floating point calculations on a Fujitsu MB90F474 16bit uC.
All float calculations are done in the main loop context. Sometimes the
result returns a garbage value. This seems to happen only when
interrupts are enabled. Note that there are no globals or shared data
involved.

If anyone has had similar problems please let me know. Any advice when
using floating point calculations would be appreciated.

Regards
Dieter
