package Standard is Pure (Standard); type Boolean is (False, True); The predefined relational operators for this type are as follows: function "=" (Left, Right : Boolean'Base) return Boolean; function "/=" (Left, Right : Boolean'Base) return Boolean; function "<" (Left, Right : Boolean'Base) return Boolean; function "<=" (Left, Right : Boolean'Base) return Boolean; function ">" (Left, Right : Boolean'Base) return Boolean; function ">=" (Left, Right : Boolean'Base) return Boolean; The predefined logical operators and the predefined logical negation operator are as follows: function "and" (Left, Right : Boolean'Base) return Boolean; function "or" (Left, Right : Boolean'Base) return Boolean; function "xor" (Left, Right : Boolean'Base) return Boolean; function "not" (Right : Boolean'Base) return Boolean; The integer type root_integer and the corresponding universal type universal_integer are predefined. type Integer is range implementation-defined; subtype Natural is Integer range 0 .. Integer'Last; subtype Positive is Integer range 1 .. Integer'Last; The predefined operators for type Integer are as follows: function "=" (Left, Right : Integer'Base) return Boolean; function "/=" (Left, Right : Integer'Base) return Boolean; function "<" (Left, Right : Integer'Base) return Boolean; function "<=" (Left, Right : Integer'Base) return Boolean; function ">" (Left, Right : Integer'Base) return Boolean; function ">=" (Left, Right : Integer'Base) return Boolean; function "+" (Right : Integer'Base) return Integer'Base; function "-" (Right : Integer'Base) return Integer'Base; function "abs" (Right : Integer'Base) return Integer'Base; function "+" (Left, Right : Integer'Base) return Integer'Base; function "-" (Left, Right : Integer'Base) return Integer'Base; function "*" (Left, Right : Integer'Base) return Integer'Base; function "/" (Left, Right : Integer'Base) return Integer'Base; function "rem" (Left, Right : Integer'Base) return Integer'Base; function "mod" (Left, Right : Integer'Base) return Integer'Base; function "**" (Left : Integer'Base; Right : Natural) return Integer'Base; The specification of each operator for the type root_integer, or for any additional predefined integer type, is obtained by replacing Integer by the name of the type in the specification of the corresponding operator of the type Integer. The right operand of the exponentiation operator remains as subtype Natural. The floating point type root_real and the corresponding universal type universal_real are predefined type Float is digits implementation-defined; The predefined operators for this type are as follows: function "=" (Left, Right : Float) return Boolean; function "/=" (Left, Right : Float) return Boolean; function "<" (Left, Right : Float) return Boolean; function "<=" (Left, Right : Float) return Boolean; function ">" (Left, Right : Float) return Boolean; function ">=" (Left, Right : Float) return Boolean; function "+" (Right : Float) return Float; function "-" (Right : Float) return Float; function "abs" (Right : Float) return Float; function "+" (Left, Right : Float) return Float; function "-" (Left, Right : Float) return Float; function "*" (Left, Right : Float) return Float; function "/" (Left, Right : Float) return Float; function "**" (Left : Float; Right : Integer'Base) return Float; The specification of each operator for the type root_real, or for any additional predefined floating point type, is obtained by replacing Float by the name of the type in the specification of the corresponding operator of the type Float. In addition, the following operators are predefined for the root numeric types: function "*" (Left : root_integer; Right : root_real) return root_real; function "*" (Left : root_real; Right : root_integer) return root_real; function "/" (Left : root_real; Right : root_integer) return root_real; The type universal_fixed is predefined. The only multiplying operators defined between fixed point types are function "*" (Left : universal_fixed; Right : universal_fixed) return universal_fixed; function "/" (Left : universal_fixed; Right : universal_fixed) return universal_fixed; The type universal_access is predefined. The following equality operators are predefined: function "=" (Left, Right: universal_access) return Boolean; function "/=" (Left, Right: universal_access) return Boolean; The declaration of type Character is based on the standard ISO 8859-1 character set. There are no character literals corresponding to the positions for control characters. They are indicated in italics in this definition. See 3.5.2. type Character is (nul, soh, stx, etx, eot, enq, ack, bel, 0 (16#00#) .. 7 (16#07#) bs, ht, lf, vt, ff, cr, so, si, 8 (16#08#) .. 15 (16#0F#) dle, dc1, dc2, dc3, dc4, nak, syn, etb, 16 (16#10#) .. 23 (16#17#) can, em, sub, esc, fs, gs, rs, us, 24 (16#18#) .. 31 (16#1F#) ' ', '!', '"', '#', '$', '%', '&', ''', 32 (16#20#) .. 39 (16#27#) '(', ')', '*', '+', ',', '-', '.', '/', 40 (16#28#) .. 47 (16#2F#) '0', '1', '2', '3', '4', '5', '6', '7', 48 (16#30#) .. 55 (16#37#) '8', '9', ':', ';', '<', '=', '>', '?', 56 (16#38#) .. 63 (16#3F#) '@', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 64 (16#40#) .. 71 (16#47#) 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 72 (16#48#) .. 79 (16#4F#) 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 80 (16#50#) .. 87 (16#57#) 'X', 'Y', 'Z', '[', '\', ']', '^', '_', 88 (16#58#) .. 95 (16#5F#) '`', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 96 (16#60#) .. 103 (16#67#) 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 104 (16#68#) .. 111 (16#6F#) 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 112 (16#70#) .. 119 (16#77#) 'x', 'y', 'z', '{', '|', '}', '~', del, 120 (16#78#) .. 127 (16#7F#) reserved_128, reserved_129, bph, nbh, 128 (16#80#) .. 131 (16#83#) reserved_132, nel, ssa, esa, 132 (16#84#) .. 135 (16#87#) hts, htj, vts, pld, plu, ri, ss2, ss3, 136 (16#88#) .. 143 (16#8F#) dcs, pu1, pu2, sts, cch, mw, spa, epa, 144 (16#90#) .. 151 (16#97#) sos, reserved_153, sci, csi, 152 (16#98#) .. 155 (16#9B#) st, osc, pm, apc, 156 (16#9C#) .. 159 (16#9F#) ' ', '¡', '¢', '£', '¤', '¥', '¦', '§', 160 (16#A0#) .. 167 (16#A7#) '¨', '©', 'ª', '«', 168 (16#A8#) .. 171 (16#AB#) '¬', soft_hyphen, '®', '¯', 172 (16#AC#) .. 175 (16#AF#) '°', '±', '²', '³', '´', 'µ', '¶', '·', 176 (16#B0#) .. 183 (16#B7#) '¸', '¹', 'º', '»', '¼', '½', '¾', '¿', 184 (16#B8#) .. 191 (16#BF#) 'À', 'Á', 'Â', 'Ã', 'Ä', 'Å', 'Æ', 'Ç', 192 (16#C0#) .. 199 (16#C7#) 'È', 'É', 'Ê', 'Ë', 'Ì', 'Í', 'Î', 'Ï', 200 (16#C8#) .. 207 (16#CF#) 'Ð', 'Ñ', 'Ò', 'Ó', 'Ô', 'Õ', 'Ö', '×', 208 (16#D0#) .. 215 (16#D7#) 'Ø', 'Ù', 'Ú', 'Û', 'Ü', 'Ý', 'Þ', 'ß', 216 (16#D8#) .. 223 (16#DF#) 'à', 'á', 'â', 'ã', 'ä', 'å', 'æ', 'ç', 224 (16#E0#) .. 231 (16#E7#) 'è', 'é', 'ê', 'ë', 'ì', 'í', 'î', 'ï', 232 (16#E8#) .. 239 (16#EF#) 'ð', 'ñ', 'ò', 'ó', 'ô', 'õ', 'ö', '÷', 240 (16#F0#) .. 247 (16#F7#) 'ø', 'ù', 'ú', 'û', 'ü', 'ý', 'þ', 'ÿ', 248 (16#F8#) .. 255 (16#FF#) The predefined operators for the type Character are the same as for any enumeration type. The declaration of type Wide_Character is based on the standard ISO/IEC 10646:2011 BMP character set. The first 256 positions have the same contents as type Character. See 3.5.2. type Wide_Character is (nul, soh ... Hex_0000FFFE, Hex_0000FFFF); The declaration of type Wide_Wide_Character is based on the full ISO/IEC 10646:2011 character set.
