as far as I know, four libraries provide long double functions:
GNU libc, Intel Math Library, OpenLibm and Musl. See Table 11 from
https://members.loria.fr/PZimmermann/papers/accuracy.pdf.
And of course we also plan to provide (correctly rounded) long double
functions, acos and cbrt are already available on the CORE-MATH page.
