Method

StringroundToString(double nb2round, int nbOfDigits)
Round to string. 
if (nbOfDigits == 0)
    return "" + Math.round(nb2round);
return new Double(round(nb2round, nbOfDigits)).toString();
introundToTop(float f)
round To Top 
if (f > (int) f)
    return (int) (f + 1);
return (int) f;
longroundToWord(long value)
Return the smallest multiple of four (4) that is greater than or equal to the given value. 
return value + ROUND_UP_AMOUNT[(int) (value % 4)];
introundToZero(float x)
round To Zero 
return (int) x;
doubleroundTwoDecimals(double value)
Rounds the passed value to two decimals after decimal point. 
return round(value, 2);
introundUp(double a)
Returns the closest int to the argument, with ties rounding up. 
return (int) Math.round(a);
longroundUp(double d)
round Up 
return Math.round(d * 10.0) / 10;
introundUP(double d)
round UP 
double dAbs = Math.abs(d);
int i = (int) dAbs;
double result = dAbs - (double) i;
if (result == 0.0) {
    return (int) d;
} else {
    return (int) d < 0 ? -(i + 1) : i + 1;
introundUp(double n)
Round the given number to the nearest whole that is greater than the number. 
return roundDown(n) + 1;
doubleroundUp(double n, int precision)
