I believe the function "ceil" is the most mathematically rigorous choice.
It rounds up (toward positive infinity) to the nearest integer equal to or
greater than the given number.

	extern double ceil(double);

	/* Round up to one decimal precision */
	double num, result;

	result = ceil(10.0 * num) / 10.0;
