NAME
       feclearexcept() - clear floating-point exception flags

SYNOPSIS
   HP Integrity Server Only
   PA-RISC Only
DESCRIPTION
       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.

USAGE
       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 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 +Onomoveflops 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.

RETURN VALUE
   Integrity Server Only
       This function always returns 0, indicating all specified exceptions were cleared.

   PA-RISC Only
       None.

ERRORS
       No errors are defined.

EXAMPLES
       Clear the underflow and inexact floating-point exception flags:
