       fegetround() - get floating-point rounding direction mode

       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

       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 state‐
       ment), 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 pre‐
       vent optimizations that can undermine the specified  behavior  of  this

       Link  in	 the math library by specifying on the compiler or linker com‐
       mand line.

       The function returns the value of the rounding direction	 macro	repre‐
       senting	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
				 the  one  with its least significant bit zero
				 is delivered.

	      Round upwards (towards +infinity).

	      Round downwards (towards -infinity).

	      Round toward zero.

       No errors are defined.

       Save, set, and restore the rounding direction.
