NAME

       fegetround() - get floating-point rounding direction mode

SYNOPSIS

DESCRIPTION

       The function gets the current rounding direction, as specified by the IEEE 754 (IEC 60559) floating-point standard.

       The default rounding direction mode is round to nearest

USAGE

       To use this function, compile either with the default option or with the and options.  Make sure your program includes

       For  HP	Integrity  servers,  specify  on  the  compiler command line or place the call to this function under the effect of an affirmative
       pragma:

       If the pragma is placed outside of any top-level declarations in a file, the pragma will apply to all declarations in the compilation  fol-
       lowing the pragma until another pragma is encountered or until the end of the file is reached.

       If  the	pragma	is  placed  at the beginning of a block (compound statement), the pragma will apply until another pragma is encountered or
       until the end of the block is reached.

       For PA-RISC, you might need to use the compiler option in order to prevent optimizations that can undermine the specified behavior of  this
       function.

       Link in the math library by specifying on the compiler or linker command line.

       For more information, see the at the following site:

RETURN VALUE

       The  function  returns  the value of the rounding direction macro representing the current rounding direction.  The return value will match
       one of the following macros, which are defined in

	      Round to nearest.  If the two nearest representable are equally near,
				 the one with its least significant bit zero is delivered.

	      Round upwards (towards +infinity).

	      Round downwards (towards -infinity).

	      Round toward zero.

ERRORS

       No errors are defined.

EXAMPLES

       Save, set, and restore the rounding direction.

NAME

       fe_dec_getround() - get decimal floating-point rounding direction mode

SYNOPSIS

DESCRIPTION

       The function gets the current decimal rounding direction.

       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.

USAGE

       To use this function, compile with the option.

       Make sure your program defines and then includes

       Specify on the compiler command line or place the call to this function under the effect of an affirmative pragma:

       If the pragma is placed outside of any top-level declarations in a file, the pragma will apply until another pragma is encountered or until
       the end of the file is reached.

       If the pragma is placed at the beginning of a block (compound statement), the pragma will apply until  another  pragma  is  encountered	or
       until the end of the block is reached.

       Link in the math library by specifying or on the linking command line.

RETURN VALUE

       The  function  returns  the  value of the decimal rounding direction macro representing the current decimal rounding direction.	The return
       value will match one of the following macros, which are defined in

	      Round to nearest.  If the two nearest representable are equally near,
				 the one with its least significant bit zero is delivered.

	      Round to nearest.  If the two nearest representable are equally near,
				 the one furthest from zero is delivered.

	      Round upwards (towards +infinity).

	      Round downwards (towards -infinity).

	      Round toward zero.

ERRORS

       No errors are defined.

EXAMPLES

       Save, set, and restore the decimal rounding direction.
