I was a bit uncertain about this, but if you want all the digits you can 
always ask sysctl:

fastnet:~$ sysctl kern.timecounter.choice
kern.timecounter.choice = iomd_timer0(q=100, f=2000000 Hz) clockinterrupt(q=0, 
f=100 Hz) dummy(q=-1000000, f=1000000 Hz)

In a similar way, we approximate disk capacities when printing them at 
boot time, and assume that anyone who needs the precise number of sectors 
will use disklabel.
