Calculates the Arc sine of a real value.
Arguments | |||
|---|---|---|---|
IN | IN | REAL | Must be in set [-1.0 .. +1.0] |
ASIN | Q | REAL | Arc-sine of the input value (in set [-PI/2 .. +PI/2]) = 0.0 for invalid input |
Example
(* FBD Program using "SIN" and "ASIN" Functions *)
(* ST Equivalence: *)
sine := SIN (angle); result := ASIN (sine); (* result is equal to angle *)
