valuegetCPUTime :: IO Integer
#

Computation getCPUTime returns the number of picoseconds CPU time used by the current program. The precision of this result is implementation-dependent.

valuecpuTimePrecision :: Integer
#

The cpuTimePrecision constant is the smallest measurable difference in CPU time that the implementation can record, and is given as an integral number of picoseconds.
