4.6.7 Square Root (SQT)
! ! ! ! Outline
The SQT command leaves the square root of the integer and real number as a calculation
result. The 32-bit integer number data cannot be used.

! ! ! ! Program Example
Input unit and output results vary depending on the integer number and real
number data.
• Integer Number
The calculation format (shown below) is different from the mathematical
square root.
: Mark of the A register
: Absolute value of the A register
That is, the result of the mathematical square root is multiplied by
. When inputting a negative number, calculate the square root of
the absolute value, and leave the negative number as a calculation
result. The calculation error is ±2.
• Real Number
Use an immediate calculation result (real number data) as an input, and leave
the square root to the real number data.
