NAME

       fe_dec_setround() - set decimal floating-point rounding direction mode

SYNOPSIS

DESCRIPTION

       The function establishes the decimal rounding direction represented by its argument round.  The round argument must equal one of the macros
       (defined in and If the argument does not match a decimal rounding direction macro, the decimal rounding direction is not changed.

       The default decimal rounding direction mode is round to nearest with half-way cases away from zero

       These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward.
