Just tested it...

int main (void){
unsigned int value;

        value = 6874;
        while (TRUE) {

                lcd_goto_rc(1,1); //display number in top left corner
                PORTD = ~PORTD; //toggle port pins
                printf ("%d.%03d", value / 1000, value % 1000);
                PORTD = ~PORTD;
                _delay_ms(50);
        }
}


...compiles and runs fine, but my scope timed it at no less than
13ms !!!!  I am running on the on-chip 1MHz RC oscillator, so that's
about 13,000 machine cycles then, ouch !
