This application illustrates the notion of an integer’s factors, and of the related property of integers called primeness, or primality. An integer is called prime if it is the product of only one distinct pair of integers. For example, 11 is prime because the only pair of integers whose product equals 11 is 1 and 11, as in 1*11 = 11 .

The control element allows the comfortable input of (long) integer values, whereby incorrect inputs by the user become impossible. It is freely adjustable in its size. The size of the represented control sub elements and the size of the displayed numbers adapt automatically. The input of the number can be made directly in the text field or indirectly by the two buttons.

HIME is a library with encryption functions and huge integer math functions. RSA public key, AES (Rijndael), RC4 secret key encryption, MD5, SHA-256 hash function, random number generation (Blum-Blum-Shub, RSA), Diffie-Hellman... Every programming language that can access a dll can use HIME: C, C++, Visual Basic, Delphi, PowerBASIC, PureBASIC.. The math functions work with huge integers that can be up to 2^31 bits long (268 million digits).

Apply math to fields (columns) in a MS Access table. Add, subtract, multiply or divide between two fields or change one field by a constant number. Access 2000 or higher required.
