(S): Data of which the square root is obtained or the number of the device where the data is stored (BSQR(P): BCD 4 digits, BDSQR(P): BCD 8 digits)

(D): Head number of the devices where the operation result will be stored (BCD 4 digits)

Internal device

Processing details

• Returns the square root of the value designated at (S), and stores the operation result in the device number designated at

Integer part

• Values that can be designated at (S) are BCD values with a maximum of 4 digits (from 0 to 9999).

• The operation results of (D) and (D)+1 are stored as their respective BCD values of between 0 and 9999.

• Operation results are rounded off from the fifth decimal place. For this reason, the fourth decimal place has an error of 1.

• Calculates the square root of the values designated by (S) and (S)+1 and stores the results at the device designated by (D).

• BCD value of a maximum of 8 digits (0 to 99999999) can be designated by (S) and (S)+1.

• The operation results of (D) and (D)+1 are stored as their respective BCD values of between 0 and 9999.

• Operation results are rounded off from the fifth decimal place. For this reason, the fourth decimal place has an error of 1.

Operation error

• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.

Error details

The data specified in (S) is not a BCD value.
