Static Methods

static double roundToPlaces(double val, int places)

Takes in val and will return it rounded to the nearest places decimal points. For example:

double num = 54.423;

num = NumberUtils.roundToPlaces(num, 1);

num is now equal to 54.4.

static double wrapDouble(double val, double min, double max)

Wraps val between min and max. For example:

for (double i = 0; i < 10; i++) {
  print(NumberUtils.wrapDouble(i, 2.0, 5.0));
}

The output of this will be:

4.0
5.0
2.0
3.0
4.0
5.0
2.0
3.0
4.0
5.0

static int wrapInt(int val, int min, int max)

Exactly the same as static double wrapDouble(double val, double min, double max), but works with integers instead.
