Description

The list of methods to do Number Round are organized into topic(s).

Method

longroundUpTo8(long val)
round Up To 
long rem = val & 7;
if (rem != 0)
    val += 8L - rem;
return val;
longroundUpToMultiple(long val, int factor)
Round a long value up to a multiple of a factor. 
assert (factor > 1);
long c = (val + factor - 1) / factor;
return c * factor;
doubleroundUpToNearest(double number, double nearest)
round Up To Nearest 
return Math.ceil(roundToPrecision(number / nearest, 10)) * nearest;
longroundUpToNearestEightBytes(long result)
round Up To Nearest Eight Bytes 
if ((result % 8) != 0) {
    result += 8 - (result % 8);
return result;
introundUpToNearestPowerOfTwoIfGreaterThanZero(final int value)
round Up To Nearest Power Of Two If Greater Than Zero 
long v = value;
v--;
v |= v >> 1;
v |= v >> 2;
v |= v >> 4;
v |= v >> 8;
v |= v >> 16;
v++;
...
introundUpToPowerOf2(int number)
round Up To Power Of 
int rounded = number >= Integer.MAX_VALUE ? Integer.MAX_VALUE
        : (rounded = Integer.highestOneBit(number)) != 0
                ? (Integer.bitCount(number) > 1) ? rounded << 1 : rounded
                : 1;
return rounded;
longroundUpToPowerOf2(long val)
round Up To Power Of 
return 1L << log2Ceiling(val);
longroundUpToPowerOf2Factor(long val, long factor)
round Up To Power Of Factor 
return (val + (factor - 1)) & ~(factor - 1);
introundUpToPowerOfTwo(int i)
Returns the smallest power of two >= its argument, with several caveats: If the argument is negative but not Integer.MIN_VALUE, the method returns zero. 
i--; 
i |= i >>> 1;
i |= i >>> 2;
i |= i >>> 4;
i |= i >>> 8;
i |= i >>> 16;
return i + 1;
introundUpToPowerOfTwo(int p_151236_0_)
Returns the input value rounded up to the next highest power of two. 
int j = p_151236_0_ - 1;
j |= j >> 1;
j |= j >> 2;
j |= j >> 4;
j |= j >> 8;
j |= j >> 16;
return j + 1;
