Synopsis

Description

i1 : t1 = cpuTime()

o1 = 157.8966208

o1 : RR (of precision 53)
i2 : for i from 0 to 1000000 do 223131321321*324234324324;
i3 : t2 = cpuTime()

o3 = 159.546263075

o3 : RR (of precision 53)
i4 : t2-t1

o4 = 1.64964227500002

o4 : RR (of precision 53)

Caveat

Under Linux, the cpu time reported is that consumed by the thread, but under MAC OS X, it is that consumed by the process.
