Method

longRoundDown(final T number)
Returns a long number by round down with specify number.
Returns 0 if number == null.
e.g: average is 3.5, then return 3. 
if (number == null) {
    return 0;
return number.longValue();
introundDown(int n, int m)
round Down 
while (n % m != 0)
    n--;
return n;
introundDown(int number, int mod)
round Down 
return number / mod * mod;
introundDown(int val, int shift)
Rounds an integer down to the nearest multiple of 2^shift . 
return val >>> shift << shift;
introundDown(int val, int to)
Round the value down to the closest value of to. 
int temp = val % to;
if (temp < 3) {
    return val - temp;
} else {
    return val + to - temp;
introundDown(long n, long m)
Round n down to nearest multiple of m. 
return (int) ((n / m) * m);
longroundDown(long size, long roundBoundary)
round Down 
return (size - (size % roundBoundary));
longroundDown(long val, long delta)
round Down 
boolean isNegative = val < 0;
val = Math.abs(val);
val = val / delta * delta;
return !isNegative ? val : -val;
introundDownTo(int a, int quanta)
round Down To 
return a & -quanta;
doubleroundDownToNearest(double number, double nearest)
round Down To Nearest 
return Math.floor(roundToPrecision(number / nearest, 10)) * nearest;
