S· D·
A square root is performed on the floating point value S; the result is stored in D
If a constant K or H used as source data, the value is converted to floating point before the
operation.
ESQR K1024 D110
X1
When the result is zero, zero flag activates.
Only when the source data is positive will the operation be effective. If S is negative then an
error occurs and error flag SM409 is set ON, SD409=7, the instruction can’t be executed.
Note: the operand value must be floating numbers, otherwise the result will be error.
