Notes on operand usage:
Refer to the function
specifications table for each device in series for
the scope of device usage.

S: source device for which square root is desired. D: result of finding square
root.
 Finds the square root of the content of the register designated by S, store
s the
result in the register designated by D. Square roots are performed entirely using
binary floating point numbers.
 If the source operand S refers to a constant K or H, the command converts that
constant into a binary floating point number for use in the operation.
 When X0=ON, finds the square root of the binary floating point number (D1, D0),
and stores the result in the register designated by (D11, D10).
X0
DESQR D0 D10
 When X2 =ON, finds the square root of K1,234 (which is automatically converted
to a binary floating point number), and stores the result in (D11, D10).

DESQR K1234 D10
