I'm writing a program to read accounting records, and in acct(4) I see
that the fields that contain the CPU utilization figures are in
"comp_t" format, for which there is a typedef above that simply says
"13-bit fraction, 3-bit exponent". Is there any more info available
(and maybe some examples) about this anywhere?

fraction = comp & 0x1fff;
exponent = comp >> 13;

value = fraction << (exponent * 3);

The exponent is base 8.
