Summary description: Logarithms and powers with (almost) 9 digits
Announcement text: ----------------------------------------------------------------------
This small package (usable with Plain TeX, LaTeX, or others) provides macros for computing logarithms in base 10 and fractional powers of 10, achieving a bit less than 9 digits of precision.
It has no dependencies and can be used on its own, but becomes more user-friendly in the presence of xintexpr package, as it provides then 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 in arbitrary precision the log10() and pow10() functions.
The documentation is included in the README.
