If the value had been stored as a float (or double) and printed with (say) %6.2f it should have been rounded off correctly. I suspect therefore that the radio display code has converted this value to an integer in 10Hz steps and failed to do its own rounding.
So it's doing something like "intfreq = (int)real_kHz * 100;" or "intfreq = (int)(real_kHz * 100.0);" If real_kHz had been 910.999999 as suggested, this would give 91099 as "intfreq" and yield the reported effect. What *should* have been done would be more like "intfreq = (int)(real_kHz + 0.005) * 100;" >You can work around this issue by entering 911.001. But I think this is a bug >that should be fixed.
