In the digital world, everything above the available integer-range (on input
and output) makes distortion. As this int-range is normally converted to the
double/float-range [-1,1], abs(signal) == 1 is normally considered as 0dB and
all the volume is measured in negative deziBel.

But in the gui I wouldn't cut off the values. It can very well be that the
mixing-stages after the guis data are scaling/limiting the signal to values
in the valid range. Just make them red so everyone is aware of the potential
problems...

Have fun,
