Method

StringroundedSatisfaction(double value)
rounded Satisfaction 
return String.format("%1$#.2f", value);
floatrounder(float value, int digits)
rounder 
return Math.round(value * Math.pow(10, digits) + 0.5) / (float) Math.pow(10, digits);
floatroundf(float value)
roundf 
float rest = value % 1f;
if (rest >= 0.5f) {
    value += 1f - rest;
} else {
    value -= rest;
return value;
longroundFileLength(long nbytes)
round File Length 
if (nbytes <= 0)
    return 0;
else if (nbytes <= 512)
    return nbytes;
else if (nbytes % 512 == 0)
    return nbytes;
else
    return (int) (nbytes / 512 + 1) * 512;
...
floatroundFloat(float value, int afterDecimalPoint)
Rounds a double to the given number of decimal places. 
float mask = (float) Math.pow(10, (float) afterDecimalPoint);
return (float) (Math.round(value * mask)) / mask;
floatroundFloatToPlace(float f, int place)
round Float To Place 
if (place < 0)
    throw new IllegalArgumentException();

    d = Math.ceil(d - 0.5);
} else if (d > 0) {
    d = Math.floor(d + 0.5);
return d;
