-===== int (signed 32-bit integer) =====+===== Int  ===== 
 + 
 +Int is signed 32-bit integer. Unsigned ints don't exist in ACS, so ''UINT_MAX can't be expressed.
  
   * ''INT_MIN = -2147483648 (-0x80000000)'' -- minimum value   * ''INT_MIN = -2147483648 (-0x80000000)'' -- minimum value
   * ''INT_MAX =  2147483647  (0x7fffffff)'' -- maximum value   * ''INT_MAX =  2147483647  (0x7fffffff)'' -- maximum value
  
-===== Short (16-bit integer) =====+===== Short ===== 
 + 
 +Shorts are 16-bit integers.
  
   * ''SHORT_MIN = -32768'' -- minimum value for signed short   * ''SHORT_MIN = -32768'' -- minimum value for signed short
Line 14: Line 18:
   * ''USHORT_MAX = 65535'' -- maximum value for unsigned short (minimum is 0)   * ''USHORT_MAX = 65535'' -- maximum value for unsigned short (minimum is 0)
  
-===== Byte (8-bit integer) =====+===== Byte ===== 
 + 
 +Bytes are 8-bit integers.
  
   * ''BYTE_MIN = -128'' -- minimum value for signed byte   * ''BYTE_MIN = -128'' -- minimum value for signed byte
Line 20: Line 26:
   * ''UBYTE_MAX = 255'' -- maximum value for unsigned short (minimum is 0)   * ''UBYTE_MAX = 255'' -- maximum value for unsigned short (minimum is 0)
  
-===== fixed (actually 32-bit integer) =====+===== fixed =====
  
-Fixed-point numbers are actually integers and have the same limits as ''int'' (''INT_MIN'' and ''INT_MAX''). But to enable [[strict typing]], there are separate limit constants for ''fixed'':+Fixed-point numbers are 32-bit integers and have the same limits as ''int'' (''INT_MIN'' and ''INT_MAX''). But to enable [[strict typing]], there are separate limit constants for ''fixed'':
  
   * ''FIXED_MIN = (fixed)-0x80000000'' -- minimum value (-32768.0)   * ''FIXED_MIN = (fixed)-0x80000000'' -- minimum value (-32768.0)
   * ''FIXED_MAX = (fixed) 0x7fffffff'' -- maximum value (slightly less than 32767.99999)   * ''FIXED_MAX = (fixed) 0x7fffffff'' -- maximum value (slightly less than 32767.99999)
