Method

floatroundTimeValue(final float defaultUnitValue, final boolean is24HourFormatting)
round Time Value 
float unit = defaultUnitValue;
int multiplier = 1;
if (is24HourFormatting) {
    while (unit > 120) {
        multiplier *= 60;
        unit /= 60;
    if (multiplier >= 3600) {
...
DoubleroundTo(double aValue, int aDigits)
Rounds a double value to digit digits after the point. 
double d = Math.pow(10, aDigits);
return new Double(Math.round(aValue * d) / d);
doubleroundTo(double d, int n)
returns the rounded result of the argument to the n digits after the decimal point. 
d *= Math.pow(10, n);
d = Math.round(d);
d /= Math.pow(10, n);
return d;
doubleroundTo(double num, int dp)
round To 
int dpM = (int) Math.pow(10, dp);
return Math.round(num * dpM) / dpM;
doubleroundTo(double val, double prec)
Rounds a double precision value to the given precision. 
return floor(val / prec + 0.5) * prec;
doubleroundTo(final double VALUE, final double TARGET)
round To 
return TARGET * (Math.round(VALUE / TARGET));
floatroundTo(float number, int base)
round To 
return Math.round(number * 10 * base) / (10f * base);
floatroundTo(float number, int numPlaces)
(Based on round() in PHP) 
if (numPlaces <= 1)
    return Math.round(number);
float exponent = (float) Math.pow(10, numPlaces);
return Math.round(number * exponent) / exponent;
floatroundTo(float val, int numPlaces)
Returns the rounded value of val to specified number of digits after the decimal point.
(Based on round() in PHP) 
if (numPlaces <= 1)
    return Math.round(val);
float exponent = (float) Math.pow(10, numPlaces);
return (Math.round(val * exponent) / exponent);
doubleroundTo100th(double w)
round Toth 
return Math.floor(w * 100 + 0.5) / 100;
