Give it’s a doc patch, I think it might fall under the obvious rule,

The patch clearly fixes a bug in the current specification and is fine,
I just wonder …

... whether we should change the "over" which somehow sounds odd. "two
divided by pi" sounds better to me than "two over pi".
I do note, however, that the following documentation uses a slightly
different wording:
"M_2_PI -Two times the reciprocal of pi."
https://www.gnu.org/software/libc/manual/html_node/Mathematical-Constants.html
Hence, while I am fine with the change, I think we should replace the
"over" wording (multiple times) and move either to "divided by" or
[(…times) the reciprocal of".
I agree. I don't have a preference for which is better, but being
consistent with other documentation might be a winning argument.
Alas, Texinfo has lousy support for formatting mathematical equations,
so that's not an option.
