Calculating the square root of 32-bit binary data
DSQRT(P)
These instructions perform a square root operation of the specified 32-bit binary data.
■Execution condition
■Description, range, data type
■Applicable devices
*1 FX and FY cannot be used.
• These instructions perform a square root operation of the 32-bit binary data specified by (s). and stores the result in (d).
The obtained square root is an integer because the decimal places are rounded down.
(s)+1, (s)
(d)
There is no operation error.
• The RnCPU and RnENCPU with firmware version "17" or later support these instructions. (Use an engineering tool with version "1.020W" or later.)
