Post Question...
Is it possible to make the robot round up?? Or does RobotC always round down with a number? Such as 2.777778 comes up as 2.00000.

Of course. You will have to make your own function, though. Here's one:

Code:
int roundup(float numtoround)
{
  if(numtoround==round(numtoround))
    numtoround--;
  numtoround++;
  return numtoround;
}


Does that help?

If you want an approach to round based on typical rules (e.g. 9.6 rounds up, 5.3 rounds down, 5.5 rounds up), you can try:

Code:
int round(float numToRound) {
  return (int) (numToRound + 0.5);
}

Or.... you can just use the round() function in ROBOTC :)

Post Re: Question...
Are we all understanding this question correctly? You want something that will always round up, or round up/down based on whether it's greater or less than x.5? I'm somewhat confused by all the different answers.

If you want to round up, use ceil(), otherwise use floor(), if you want to round off, like most humans do, use round().
