 ACSUtils provides a full set of functions to round fixed-point numbers to integers. ACSUtils provides a full set of functions to round fixed-point numbers to integers.
  
-<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 warning>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.

-==== Rounding modes ====+===== Rounding modes =====
  
 There are four rounding modes: There are four rounding modes:
Line 27: Line 29:
 ^  -1.8|        -2|        -2|       -1|        -1| ^  -1.8|        -2|        -2|       -1|        -1|
  
-==== Rounding functions in ACSUtils ====+===== Functions =====
  
 Every rounding mode is available as two functions: Every rounding mode is available as two functions:
   * Functions without the ''i'' prefix return a fixed, e.g. ''floor(2.3) == 2.0''.   * Functions without the ''i'' prefix return a fixed, e.g. ''floor(2.3) == 2.0''.
-  * Functions with the ''i'' prefix return an int, e.g ''ifloor(2.3) == 2''.+  * Functions with the ''i'' prefix return an int, e.g. ''ifloor(2.3) == 2''.
  
 ^ Mode  ^ fixed result ^ int result ^ ^ Mode  ^ fixed result ^ int result ^
