hi everyone

fpc with softfloat seems to work quite well on arm (le). i've run into a strange problem, though. i've got code that looks like this:

  writeln(stderr, 'gain is ', round(scan.avge.tip.gain * 100));
  writeln(stderr, 'gain is ', format('%.0f', [scan.avge.tip.gain * 100]));

sometimes i get an eoverflow exception on the second line. this depends on the value of scan.avge.tip.gain. here's a trace - might not be very helpful:

gain is -10
An unhandled exception occurred at $0001D73C :

any help would be appreciated!

thanks

update: this happens if i try FloatToStrf of any negative number. works with positive numbers, though.

If it helps to isolate problem (anyone?)...
it seems to work if the variable is declared as float type 'currency' but not for any other type. However any / or * operation returns runtime error 207.
