       feclearexcept() - clear floating-point exception flags

   HP Integrity Server Only
   PA-RISC Only
       The  function  clears  the exception flags represented by its argument.
       The argument can be constructed	as  a  bitwise	OR  of	the  exception
       macros: and represents all the floating-point exceptions.

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

       For 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 +Onomoveflops compiler option in
       order  to prevent optimizations that can undermine the specified behav‐
       ior of this function.

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