The list of methods to do Decimal are organized into topic(s).

Method

StringdecimalAlign(int width, int precision, String s)
Formats a String representation of a decimal number to a stated precision and total width. 
String fraction = "";
String whole = "0.";
int dot = s.lastIndexOf('.');
if (dot >= 0) {
    whole = s.substring(0, dot + 1);
    fraction = s.substring(dot + 1);
if (fraction.length() > precision) {
...
intdecimalDigit(final long value, final int i)
Return a particular digit value from a given number 
int result = (int) (Math.abs(value) % Math.pow(10, i));
if (i > 1) {
    result /= Math.pow(10, i - 1);
return result;
intdecimalDigitCount(int num)
decimal Digit Count 
if (num < 10)
    return 1;
if (num < 100)
    return 2;
if (num < 1000)
    return 3;
if (num < 10000)
    return 4;
...
StringdecimalDump(final byte[] bytes)
Dumps the byte array into a string as a series of 8bit decimal numbers 
StringBuffer buffer = new StringBuffer();
for (byte b : bytes) {
    buffer.append(Byte.toString((byte) (b & SINGLE_BYTE_SIGN_MASK)));
    buffer.append(" ");
return buffer.toString();
floatdecimalPart(float f)
Returns the decimal part of a float, regardless of its sign. 
return f - (int) f;
floatdecimalPart(float number)
decimal Part 
int integerPart = (int) number;
return number - integerPart;
floatdecimalPlace(float theValue, int theDecimalPlaces)
decimal Place 
final float myDecimalPlaceClamp = (float) Math.pow(10, theDecimalPlaces);
return ((int) (theValue * myDecimalPlaceClamp)) / myDecimalPlaceClamp;
doubledecimalPlaces(double value, int precision)
decimal Places 
return (double) Math.round(value * Math.pow(10.0D, (double) precision))
        / Math.pow(10.0D, (double) precision);
doubledecimalPlaces(double value, int precision)
Sets a fixed number of digits after the decimal point. 
return (double) Math.round(value * Math.pow(10, precision)) / Math.pow(10, precision);
doubledecimalRound(double value, int roundPlaces)
decimal Round 
int temp = (int) ((value * Math.pow(10, roundPlaces)));
return (((double) temp) / Math.pow(10, roundPlaces));
