-<note important>Current GZDoom provides built-in functions [[zdoom>Floor_(ACS_function)|floor]], [[zdoom>ceil]] and [[zdoom>round]], but these functions aren't available in Zandronum 3.0 **silently return 0** there, because all unimplemented built-in ACS functions return 0.+<note important>Current GZDoom provides built-in functions [[zdoom>Floor_(ACS_function)|floor]], [[zdoom>ceil]] and [[zdoom>round]], but these functions aren't available in Zandronum 3.0 and **silently return 0** there, because all unimplemented built-in ACS functions return 0.
  
 Before using ACSUtils, rename either the built-in functions (by editing ''zspecial.acs'') or the ACSUtils functions (by editing ''acsutils.acs'') to something else. Otherwise, ACSUtils won't compile. Before using ACSUtils, rename either the built-in functions (by editing ''zspecial.acs'') or the ACSUtils functions (by editing ''acsutils.acs'') to something else.
