Explanation
 The square root of the value in
S is calculated, and the result is stored in D.
 S: Source device; D: Device in which a result is stored
 The value in S can only be a positive value. If the value in S is a negative
value, an error will occur, and the instruction will not be executed.
 The value stored in D is an integer. The fractional part of a square root
calculated is dropped. If the fractional part of a square root calculated is
dropped, a borrow flag will be ON.
 If the value in D is 0, a zero flag will be ON.
Example

When X20 is ON, the square root of the value in D0 is calculated, and the
result is stored in D12.
