Thanks.  How did I miss the obvious?  The results are still strange:

	chuck at zeta:~$ cat roundtest.c
	#include <stdio.h>
	#include <math.h>

	int main()
	{
    		printf("%f\n", round((double) 390.0));
	}
	chuck at zeta:~$ gcc -lm -o roundtest roundtest.c
	chuck at zeta:~$ ./roundtest
	2.896811
	chuck at zeta:~$

Why is it rounding 390.0 and getting 2.896811?
