Unified Tables for Exponential and Logarithm Families

Accurate table methods allow for very accurate and efficient evaluation of elementary functions. We present new single-table approaches to logarithm and exponential evaluation, by which we mean that a single table of values works for both log( x ) and log(1 + x ), and a single table for e x and e x − 1. This approach eliminates special cases normally required to evaluate log(1 + x ) and e x − 1 accurately near zero, which will significantly …
