Abstract: Various example embodiments relate to computation of a shared exponent for numbers. A plurality of bit vectors may be obtained. A bitwise OR-operation may be performed for the plurality of bit vectors to obtain an auxiliary bit vector. The shared exponent may be then determined based on a position of a most significant bit having value equal to one in the auxiliary bit vector. The representation for the plurality of bit vectors may be then determined based on the shared exponent. Apparatuses, methods, and computer programs are disclosed.

Abstract: A method is provided for distributing information or services through a network. A piece of information or service to be distributed is composed and a list of intended recipients is compiled (301, 301?, 302, 601, 602). Said piece of information or service is released (304, 304?, 603) so that it becomes accessible to the recipients appearing on said list. As a response to an indication (305, 401, 606) of a certain recipient having accessed (605) said piece of information or service, an account associated with said certain recipient is credited (306, 608).
