I did test this at one point and was also surprised that sqrt(x) seemed
slower than **.5. However I found out otherwise while preparing a timeit
script to demonstrate this observation. Unfortunately, I didn't save the
precise script I used to explore this issue the first time. On my system
for arrays with more than 2 elements, sqrt is indeed faster. For smaller
arrays, the different is negligible, but inches out in favor of **0.5.
