Symbol:
S
：
Source device Word/Double word
D
：
Device in which the result is stored Word/Double word
Explanation:
1. After the square root of the value in the device specified by S is calculated, the integer part is
stored in the device specified by D, and the fractional part is stored in the device specified by
D+1.
2. The 16-bit value in S should be within the range between 0 and 9,999, and the 32-bit value in
S should be within the range between 0 and 99,999,999.
3. If the instruction BSQR is used, the square root is rounded down to the fourth decimal place.
4. If the instruction DBSQR is used, the square root is rounded down to the eighth decimal place.
5. If the operation result stored in D is 0, SM600 is ON.
Example 1:
After the square root of the value in D0 is calculated, the integer part is stored in Y0, and the
fractional part is stored in Y1.
