Method

doubleroundUpNumberByUsingMultipleValue(double number, double multiple)
Round up number by using multiple value. 
double result = multiple;
if (number % multiple == 0) {
    result = number;
} else if (number % multiple != 0) {
    if (number >= 0) {
        int division = (int) ((number / multiple) + 1);
        result = division * multiple;
    } else {
...
introundUpPOT(int value)
round Up POT 
return 1 << (32 - Integer.numberOfLeadingZeros(value - 1));
introundUpPow2(int x)
Rounds an integer up to the next power of 2. 
if (x <= 0) {
    return 1;
} else if (x > 0x40000000) {
    throw new IllegalArgumentException(
            "Rounding " + x + " to the next highest power of two would exceed the int range");
} else {
    x--;
    x |= x >> 1;
...
introundUpPower2(int i)
round Up Power 
i--;
i |= i >> 1;
i |= i >> 2;
i |= i >> 4;
i |= i >> 8;
return (i | (i >> 16)) + 1;
introundUpPower2(int v)
round Up Power 
switch (Integer.bitCount(v)) {
case 0:
    return (1);
case 1:
    return (v);
default:
    return (Integer.highestOneBit(v) << 1);
doubleroundUpTo(double in, double del)
round in up to the next even multiple of del 
int n = (int) (in / del);
double ret = n * del;
if (ret == in)
    return (ret);
return (ret + del);
introundUpTo(int a, int quanta)
round Up To 
return (a + (quanta - 1)) & -quanta;
longroundUpTo(long i, long multiple)
round Up To 
return (i + multiple - 1L) & ~(multiple - 1L);
introundUpTo100(int n)
round Up To 
int rem = n % 100;
if (rem == 0)
    return n;
return n + (100 - rem);
longroundUpTo8(final long number)
round Up To 
return ((number + 7) / 8) * 8;
