Method

doubleroundOff(double fraction, int precision)
Rounds off fraction to the given amount of precision. 
int i = 0;
int finalNum = 1;
while (i++ < precision) {
    finalNum *= 10;
return (double) Math.round(fraction * finalNum) / finalNum;
doubleroundOffAmt(double dAmt)
round Off Amt 
return Math.round(dAmt * 10000000000.0) / 10000000000.0;
StringroundOffFileCount(int fileCount)
round Off File Count 
String fileCountStr = String.valueOf(fileCount);
if (fileCountStr.length() == 1) {
    fileCountStr = "0" + fileCountStr;
return fileCountStr;
doubleroundOffTo2DecPlaces(double val)
round Off To Dec Places 
return Math.round(val * 100) / 100;
double[]roundOffValues(double[] doubles)
round Off Values 
double[] returnDoubles = new double[doubles.length];
for (int i = 0; i < doubles.length; i++) {
    returnDoubles[i] = Math.round(doubles[i]);
return returnDoubles;
doubleroundPhred(final double value, final double phredScorePrecision)
Round a Phred scaled score to precision phredScorePrecision 
return Math.round(value / phredScorePrecision) * phredScorePrecision;
introundPos(final float a)
Round a positive a 
return (int) (a + 0.5f);
introundPositive(float value)
Returns the closest integer to the specified float. 
return (int) (value + 0.5f);
introundPositive(float x)
round Positive
