Delphi Variable sizes

Although we are on a high programming language, the size of variables is very important when you are working with untyped / binary files and also socket programming, here is the basic types and also their sizes

Type  Storage size                        Range            
 
 Byte       1                             0 to 255
 ShortInt   1                          -127 to 127
 Word       2                             0 to 65,535
 SmallInt   2                       -32,768 to 32,767
 LongWord   4                             0 to 4,294,967,295
 Cardinal   4*                            0 to 4,294,967,295
 LongInt    4                -2,147,483,648 to 2,147,483,647
 Integer    4*               -2,147,483,648 to 2,147,483,647
 Int64      8    -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
 
 Single     4     7  significant digits, exponent   -38 to +38
 Currency   8    50+ significant digits, fixed 4 decimal places
 Double     8    15  significant digits, exponent  -308 to +308
 Extended  10    19  significant digits, exponent -4932 to +4932
 
 * Note : the Integer and Cardinal types are both 4 bytes in size at present (Delphi release 7), but are not guaranteed to be this size in the future. All other type sizes are guaranteed.

Have a good and nice day everyone.

I'm trying to leaving my traces for anyone who would venture the world of programming

hehehehe :D
