Some embedded platforms lack support for floating point numbers, and even when floating point is supported there are situations where fixed point has some benefits. Conversion from fixed point to floating point before transmitting over the serial port is an expensive operation that is preferable to avoid.
Currently it would appear that the "Gain" setting on each plot channel is limited to 6 digits after the decimal point. My specific need is a scale factor of 0.00000005960464478 (i.e. a divide by 2^24 = 16777216), which would convert a fixed point Q24 number to floating point.
Ideally a configuration option would allow the user to select the appropriate Q number format (https://en.wikipedia.org/wiki/Q_(number_format)). A quick workaround is to simply support smaller scale factors (more decimals).
