delphi 整数类型的表述

同一行的，表示的是相同范围的数。
shortint ---- int8 -128..127
smallint ---- int16  SHORT -32768..32767
integer  Longint ----- int32 LONG
int64 -----LONGLONG Largeint   LONG64
NativeInt ---- IntPtr    INT_PTR LONG_PTR SSIZE_T
下面是无符号数
byte ---- UInt8 UCHAR
Word ---- UInt16 USHORT
cardinal LongWord ---- UInt32 ULONG UINT DWORD ULONG32           0..4294967295
UInt64--------- DWORDLONG   ULONGLONG ULONG64 DWORD64 Largeuint
NativeUInt ---------- UIntPtr     UINT_PTR ULONG_PTR DWORD_PTR SIZE_T
