fegetround() function determines the current
  floating-point rounding mode, and the fesetround()
  function sets the current rounding mode to round. The
  rounding mode is one of FE_TONEAREST,
  FE_DOWNWARD, FE_UPWARD, or
  FE_TOWARDZERO, as described in
  fenv(3).
fegetround() routine returns the current rounding
  mode. The fesetround() function returns 0 on success
  and non-zero otherwise; however, the present implementation always succeeds.
fegetround() and
  fesetround() functions conform to
  ISO/IEC 9899:1999 (“ISO C99”).
