Description

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

Method

intfloorPositive(float value)
Returns the largest integer less than or equal to the specified float. 
return (int) value;
floatfloorPot(float value)
floor Pot 
float returnValue = 0.0f;
for (float newValue = 2.0f; newValue < value; newValue *= 2.0f) {
    returnValue = newValue;
return returnValue;
intfloorPOT(int n)
floor POT 
return ceilMaskPOT(n) + 1 >>> 1;
intfloorPowerOf2(final int n)
Computes the floor power of 2 within the range [1, 2^30]. 
if (n <= 1) {
    return 1;
return Integer.highestOneBit(n);
intfloorPowerOf2(final int x)
Rounds down the value to the nearest lower power^2 value. 
return (int) Math.pow(2, (int) (Math.log(x) / LOG2));
intfloorPowerOf2(int n)
Computes the floor power of 2 within the range [1, 2^30]. 
if (n <= 1) {
    return 1;
int f = ceilingPowerOf2(n);
if (f <= n) {
    return f;
return f >> 1;
...
intfloorPowerOfTwo(final int a)
floor Power Of Two 
if (a <= 0) {
    throw new IllegalArgumentException("a [" + a + "] must be > 0");
return Integer.highestOneBit(a);
longfloorSec(long milli)
floor Sec 
return (milli / 1000L) * 1000L;
longfloorSec(long valueMs)
floor Sec 
return convertToSec(valueMs) * SECOND;
intfloorSqrt(long i)
floor Sqrt 
return (int) Math.sqrt(i);
