I had a person bring an interesting problem to me that appears to involve some sort of rounding inside awk. I've verified this with awk and nawk on Solaris as well as with gawk 3.1.5 on a Linux box. The original code fragment he brought me was thus: for (index=0; index < 1; index=index+.1) ...

NAME

       fesetround() - set floating-point rounding direction mode

SYNOPSIS

DESCRIPTION

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

       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 a zero value if and only if the argument is equal to a rounding direction macro.

ERRORS

       No errors are defined.

EXAMPLES

       Save, set, and restore the rounding direction.
