poormanlog – Logarithms and powers with (almost) 9 digits

This small pack­age (us­able with Plain , , or oth­ers) pro­vides macros for com­put­ing log­a­rithms in base 10 and frac­tional pow­ers of 10, achiev­ing a bit less than 9 dig­its of pre­ci­sion.

The pack­age has no de­pen­den­cies and can be used on its own, but be­comes more user-friendly in the pres­ence of the xin­t­expr pack­age, as it then pro­vides log10() and pow10() func­tions and op­tion­ally patches the ** or ^ power op­er­a­tors to use those. This us­age will be­come ob­so­lete if and when xin­t­expr will na­tively im­ple­ment log10() and pow10() func­tions in ar­bi­trary pre­ci­sion.

The doc­u­men­ta­tion is in­cluded in the README.
