[I just noticed si_prefix is declared to take 'unsigned int' which is
probably wrong)

Why don't you change the si_prefix/iec_binary_prefix to return NULL
rather than asserting, then we end up with something like:

   exponentstr = NULL;
   if (unit && value->base == 10) {
       exponentstr = si_prefix(value->exponent);
   } else if (unit && value->base == 2) {
       exponentstr = iec_binary_prefix(value->exponent);
   }
   if (exponentstr) {
       monitor_printf(mon, "%s", exponentstr);
   } else if (value->exponent) {
