I have a device that produces audible tones based on Hz and I need to produce a tone of 2030.464 Hz. The problem is my device won't accept an entry of thousandths, on hundredths. Can I change the octave so my device will accept an input, or do I just need to round down? Also, assume that, even at a frequency that is normally inaudible, the device will reduce to make it audible. Thank you
