Using floating-point unit (FPU)
you also might look into the DSP library

Already seen it, explains benefits of the FPU, though never seen a example code or init it ...
In OpenODS Eclipse trough ARM-USB-TINY-H i declare variable as float as i see here, so + - * / should work, weeell no since i got error for making those arithmetic operations "undefined reference to `__aeabi_f2uiz'"
while compiling.

Any ideas ?
