Function - Calculates the square root of the input.
IN : REAL/LREAL Real value
Q : REAL/LREAL Result: square root of IN
In LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung. In IL, the input must be loaded in the current result before calling the function.
Q := SQRT (IN);
(* The function is executed only if EN is
TRUE *)
(* ENO keeps the same value as EN *)
Op1: LD IN
SQRT
ST Q (* Q is: SQRT
(IN) *)
