Claim:
1. A device for determining an estimate of a logarithmic value of an input variable, the device comprising: an approximation unit configured to (i) determine a first variable that corresponds to an estimate of an integer component of the logarithmic value of the input variable and (ii) determine a second variable that corresponds to an estimate of a non-integer component of the logarithmic value of the input variable; a determination unit configured to determine a first correcting quantity based on the second variable, wherein the determination unit is configured to determine at least one second correcting quantity that is dependent on the second variable and the assessment unit is configured to assess the estimate of the logarithmic value of the input variable by combining the first variable with the second variable and at least one of the first correcting quantity and the at least one the second correcting quantity; and an assessment unit configured to assess the estimate of the logarithmic value of the input variable by combining the first variable with the second variable and the first correcting quantity.
