All matter is made of atoms. Atoms are the smallest particle of matter. They are so small that you cannot see them with your eyes or even with a standard microscope. A standard sheet of paper is about a million atoms thick.
Answer Wiki. The int type is a 4-byte signed integer. There are also tinyint (1 byte), smallint (2 bytes), and bigint (8 bytes), and unsigned versions of all of these. As Apostolos mentioned, the docs for all the numeric types are here: http://dev.mysql.com/doc/refman/...
All replies. int is always 32bit in C#. internally, the references are using 32bit or 64bit, depending, what kind of process/CPU you have. That means, that structures/classes can be different in size, depending on the process on which your C#-program is running. BUT an int variable is always 32 bit.
