// 2// There are many ways of rounding...
Math.ceil(5.5) // Answer 6, rounds up.
Math.round(5.5) // Answer 6, rounds to the closest whole number.
Math.floor(5.5) // Answer 5, rounds down.
// ceil is short for ceiling(up), floor is down...//The Math.ceil() function always rounds a
//number up to the next largest integer.
//Note: Math.ceil(null) returns integer 0
//and does not give a NaN error.
Math.ceil(.95); // 1
Math.ceil(4); // 4
Math.ceil(7.004); // 8
Math.ceil(-0.95); // -0
Math.ceil(-4); // -4
Math.ceil(-7.004); // -7
Math.ceil(x); //This equals the next whole number after x. X must be a double.
//Example use:
x = Math.ceil(x);
//Now x is equal to x rounded up.Math.ceil()
