Sounds good to me re breaking float pow.  It's doing
something
really weird in 2.2.1 anyway.  pow(3.,500.,7.) returns
2, pow(3,5000,7) returns 2, pow(3.,5000.,7.) returns 4.0,
but 3.**5000. returns inf.  pow(3.,50000.,7.) returns NaN.

The roundoff errors though don't bother me especially
more than any other float roundoff errors, e.g.
 3.**99+1-3.**99 = 0.
