I get an error for rounding up:

  Using llvm-libc
  MPFR library: 4.1.0       
  MPFR header:  4.1.0 (based on 4.1.0)
  Checking function sinf with MPFR_RNDU
  libm wrong by up to 3.40e-11 ulp(s) [1] for x=-0x1.47d0fep+34
  sin      gives -0x1p+0
  mpfr_sin gives -0x1.fffffep-1
  Total: errors=1 (0.00%) errors2=0 maxerr=3.40e-11 ulp(s)
