The RMS is defined as the root-mean-squared deviation *from the mean*, not from zero ... so I think the whole test suite needs fixing.

All but one of the test cases require solutions truncated to an arbitrary precision. The other expects an exact solution, but not quite the exact solution I arrive at. Maybe RMS has a special connotation I've forgotten when it involves complex numbers?
