S: source device for which square root is desired D: result of finding square root.
When the square root is taken of the content of the register designated by S, the
result is temporarily stored in the register designated by D. Taking square roots
is performed entirely using binary floating-point numbers.
If the source operand S refers to a constant K or H, the command will transform
that constant into a binary floating point number for use in the operation.
When X0=On, the square root is taken of the binary floating point number (D1,
D0), and the result is stored in the register designated by (D11, D10).

When X2 =On, the square root is taken of K1,234 (which has been automatically
converted to a binary floating-point number), and the results stored in (D11,
D10).
