Abstract (en)

[origin: DE19906559C1] The calculation method has the number values for a non-linear function entered as an input word together with an associated codeword with a floating point input format (EFf), received by an input multiplexer (M1) of an electronic data processor and converted into an intermediate fixed point format (ZF), divided into a coding region (Kc) and a lower value position region (Gc), subsequently combined via an output multiplexer (M2), to provide the output format(AF). An Independent claim for a digital-electronic system is also included.
