Title:
  libc has broken cos implementation

Status in glibc package in Ubuntu:
  Fix Released
Status in glibc source package in Xenial:
  Fix Committed

Bug description:
  glibc 2.23 has a broken implementation of cos.

  To see that, enter "=cos(1.5689793435451356)" into gnumeric or localc.  A correct result is close
  to 0, but libc and thus gnumeric/localc return ~1.

  As per https://sourceware.org/bugzilla/show_bug.cgi?id=20357 this is
  fixed in 2.24

  Suggestion: backport fix for that.

  
  Seen on Ubuntu 16.04 (well, Mint 18).
