EXTRACT (FUN)¶

FUNCTION EXTRACT : BOOL

Returns bit number N of value X

Example in ST:

FLAG := EXTRACT(X:=81, N:=4);  (* Result : TRUE, because 81 is binary 1010001, so the bit '4' is 1 *)
FLAG := EXTRACT(X:=33, N:=0);  (* Result : TRUE, because 33 is binary 100001, so the bit '0' is 1 *)

InOut:

Scope	Name	Type	Comment
