Poormanlog – Logarithms and powers with (almost) 9 digits

This small package (usable with Plain ε-TeX, LaTeX, or others) provides two expandable macros computing logarithms in base 10 and fractional powers of 10, for inputs and outputs with 9 digits.

It used to serve as a bootstrap to the xintexpr multi-precisions support of logarithms and exponentials. As of xintexpr 2.0a1, it has been retired from this role and will not receive further updates in the future, save for bug fixes.
