I would like to work on this.

This requires log1pf, which must be implemented first. Our log1p is based on https://www.netlib.org/fdlibm/s_log1p.c, but I couldn't find the single-precision implementation for it. Is it there ? If not, what source must we then follow for log1pf ?

FreeBSD has log1pf implementation : https://svnweb.freebsd.org/base/release/12.2.0/lib/msun/src/s_log1pf.c?revision=367086&view=markup

Use FreeBSD v12.2.0. Our log1p probably needs to be updated, as I imagine that the fdlibm implementation is somewhat out-of-date.

log1pf, in turn, requires roundf. It isn't needed for the function's implementation, but is required at examples/index.js.
Should I go ahead for roundf ?
