<p><it>Abstract</it>—Two trees are used sequentially to calculate an approximation to 1/<it>A</it>, where 1 ≤<it>A</it> < 2. These trees calculate the logarithm and exponential, and the division (reciprocation) process can be described by 1/<it>A</it>=<it>e</it><super>−ln<it>A</it></super>. For bit skip accuracy of six to 10, this logarithmic-exponential method uses significantly less hardware with respect to the scheme in [<ref rid="BIBC13263" type="bib">3</ref>], and the delays may be greater or less than those of [<ref rid="BIBC13263" type="bib">3</ref>], depending on the method used and the minimum bit skip.</p>
