Abstract:
1. A digital electronic method for increasing the calculation accuracy in non-linear functions, comprising the steps of: inputting, for processing, into a first multiplexing device of an electronic data processing device with 2 with the point being at an undetermined location, wherein S represents the plus or minus sign, Ül f the locations with the highest values are used only in case of overflow, M f the locations with the uniform width m and Al f the locations with the lowest value, which are not used, and the index “ f ” is the coded control word of the length F, transforming said value in the data processing device to an intermediate format with (m+1) locations and a fixed point location, (fixed point representation) wherein the locations Ül dividing the number range which is represented at the output of the first multiplex device by the intermediate format ZF into C intervals of partially different sizes which cover the whole number range of ZF without overlapping and without gaps, and dividing the intermediate format ZF into a range K
