[various rounding functions deleted]

Hey, this isn't comp.lang.c, and ANSI C isn't COBOL, guys!  Seriously, I 
immediately ran into the same problem trying to use C for financial 
apps - no library functions to round to nearest integer.  So I did the 
following initially (later I came up with a compact version which is 
not available here, but based on this):

#include <math.h>

int roundit(float);

int roundit(notround)
float notround;
{
	int itround;

	itround = (int)notround;
	if ( ( notround - itround ) >= 0.5 )
	itround = ++itround;
	else if ( ( notround - itround ) < 0.5 )
	itround = itround;
	return itround;
}

This looks like it is ANSI C compatible (I think I have it compiled using 
K&R).  I have this in a utilities file which I include in any financial 
apps; you call the function and pass notround to it, and it returns 
itround.  It has always worked for me on several machines, but the caveat 
is that I am not a professional programmer by any wild stretch of 
imagination.

Just my $0.02 of code.
