            Bug ID: 99338
           Summary: -f and -l variants of cmath functions missing (e.g.
                    std::cosf() and std::cosl())
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tilman.vogel at web dot de
  Target Milestone: ---

According to 

https://en.cppreference.com/w/cpp/numeric/math/cos

and the references listed in the corresponding discussion page, the math
functions
with explicit precision like `std::cosf()` and `std::cosl()` are supposed to be
standard.

They seem to be missing from libstdc++-10.2.1 . 

Can this be fixed or is it a deliberate choice?
