Method

voidRound(Object in)
Round 
if (in == null)
    return;
if (in instanceof int[]) {
    int[] inn = (int[]) in;
    for (int i = 0, s = inn.length; i < s; i++)
        inn[i] = (int) (int) inn[i];
} else {
    for (int i = 0, s = ((Object[]) in).length; i < s; i++)
...
Stringround(String num, int length)
round 
if (num.indexOf('.') < 0)
    return num;
if (num.length() <= length)
    return num;
if (num.charAt(length) >= '5' && num.charAt(length) != '.') {
    char[] temp = new char[length + 1];
    int ct = length;
    boolean rounding = true;
...
intround4(int n)
round 
return n + round4[n & 3];
intround_pow2(int x)
Round_pow2. 
int ans = 1;
while (ans < x) {
    ans *= 2;
return ans;
intround_up(int value, int multiple)
Round a number up to a given multiple. 
return (((value - 1) / multiple) + 1) * multiple;
introundAdd(double a, double b)
Addieren und dann das Ergebnis runden. 
return round(a + b);
introundAndCrop(final float x, final int min, final int max)
First calls Math.round with x and then crops the resulting value to the range min to max. 
final int rx = Math.round(x);
return crop(rx, min, max);
introundByGridSize(int value)
round By Grid Size 
value = value + (GRID_SIZE / 2);
value = value / GRID_SIZE;
value = value * GRID_SIZE;
return value;
introundByte(final double value)
Rounds a float value and clamp the result between 0 and 255 inclusive. 
return (int) Math.min(Math.max(Math.round(value), 0), 255);
introundBytesToGB(long bytes)
Round bytes to GiB (gibibyte) 
return Math.round((float) bytes / 1024 / 1024 / 1024);
