FIX16Align	T_FIX16

Inputs

VAR_INPUT
    in : T_FIX16;
    n  : BYTE(0..15);
END_VAR

Name	Type	Description
in	T_FIX16	Fixed-point number whose resolution is to be modified
n	BYTE(0..15)	Fixed-point number whose resolution is to be modified

Example:

PROGRAM FIXALIGN
VAR
    q8, q4 : T_FIX16;
    result : LREAL;
END_VAR

q8 := LREAL_TO_FIX16( 0.6, 8 );
result := FIX16_TO_LREAL( q8 );(* The result is: 0.6015625 *)

q4 := FIX16Align( q8, 4 );
result := FIX16_TO_LREAL( q4 );(* The result is: 0.5625 *)
