Abstract
A computer program product, an apparatus, a functionally safe programmable controller and a method for processing data, wherein an uncoded real number x is converted into a logarithmic number system (LNS) coded integer xvia a predetermined conversion rule for a logarithmic number system (LNS) in accordance with the relationship: x=sgn(x)·2+Id|x|·2, where sgn(x) denotes a sign function of the uncoded real number x, Id|x| denotes a binary logarithm of the uncoded real number x, m denotes a first exponent and n denotes a second exponent, and the LNS-coded integer xis coded into an arithmetically coded integer xvia arithmetic coding such that the required integer operations is reduced.
