SYNOPSIS
.In fenv.h
.Fd "#pragma STDC FENV_ACCESS ON" int fegetround void int fesetround "int round"
DESCRIPTION
The 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).
RETURN VALUES
The fegetround routine returns the current rounding mode. The fesetround function returns 0 on success and non-zero otherwise; however, the present implementation always succeeds.
