Method

doubleroundDoubleToPlace(double d, int place)
round Double To Place 
if (place < 0)
    throw new IllegalArgumentException();
if (place > 9)
    throw new IllegalArgumentException();
long factor = (long) Math.pow(10, place);
return ((double) Math.round(d * factor)) / factor;
doubleroundDoubleValue(double value)
Rounds a double value to the first two digits. 
double roundedValue = Math.round(value * 100) / 100.0;
return roundedValue;
introundDown(double a)
Returns the closest int to the argument, with ties rounding down. 
double r = a % 1;
if (r < 0)
    r += 1;
return r == 0.5 ? (int) Math.round(a) - 1 : (int) Math.round(a);
doubleroundDown(double amt, double digits)
round Down 
double powValue = Math.pow(10, digits);
amt = amt * powValue;
amt = ((int) amt);
amt = amt / powValue;
return amt;
introundDown(double n)
Round the given number to the nearest whole that is smaller than the number. 
return (int) n;
doubleroundDown(double num)
round Down 
return Double.valueOf(String.format("%.2f", num));
doubleroundDown(double val, int decimals)
Cut a value to given number of decimals. 
double pow = Math.pow(10, decimals);
return Math.floor(val * pow) / pow;
doubleroundDown(double value, double units)
round Down 
double scaled = value / units;
return Math.floor(scaled) * units;
introundDown(double value, int gridSize)
round Down 
return (int) (Math.floor(value / gridSize) * gridSize);
introundDown(final float realNumber)
Round the number down to the closest integer 
return (int) Math.round(Math.floor(realNumber));
