' The Whetstone-Benchmark watts 1976 in the nationwide Physical Laboratory (USA) develops,
' around the performance there entwickelter computer To detect.
' Whetstone uses for Messungen Gleitkommazahl-Operationen, but
' too Ganzzahl-Arithmetik and Zugriffe on area-items.
'
'   Performs one million Whetstone instructions, a number of times, then
'   prints the execution speed in k Whetstone Instructions by Second
'   (kWIps). For example, if ntimes = 1, and the execution time is 1
'   second, then the result is 1000 kWIps.
