--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery =

Last-bit rounding issues aren't bugs except for functions such as sqrt or=20
fma that are fully defined by bindings to IEEE 754 operations.

I'd encourage using exp10 (in glibc for a very long time, standardized in=20
C23) instead of pow with first argument 10; that probably won't improve=20
last-bit accuracy, but is likely to be faster.
