
The square root of the binary floating-point value in S is calculated, and
the result is stored in D .

S : Source device; D : Device in which a result is stored

If S is a floating-point value, the instruction will be used to calculate the
floating-point value.

If an operation result is 0, a zero flag will be ON.

SM1064 is the zero flag in an Ox motion subroutine, and SM968 is the
zero flag in O100.

SM1049 is the operation error flag in an Ox motion subroutine, and
SM953 is the operation error flag in O100.

If the value in S is not a positive value, an operation error will occur, the
instruciton will not be executed, an operation error flag will be ON, and
the error code 16#0E19 will appear.

When X0.0 is ON, the square root of the binary floating-point value in
(D1, D0) is calculated, and the result is stored in (D11, D10).
