Abstract

A process is provided for monitoring the conversion of numerical values from a first to a second format, where before and after the conversion, the modulo residue of the corresponding numerical value is calculated and compared with the corresponding residue after the conversion. In this way it is possible to effect error-free monitoring of such a conversion, especially of computer data, without great hardware expenditure.
