Method

double[]toDoubles(byte[] bytes)
to Doubles 
int size = toInt(bytes, 0);
double[] result = new double[size];
int offset = SIZEOF_INT;
for (int i = 0; i < size; i++) {
    result[i] = toDouble(bytes, offset);
    offset += SIZEOF_LONG;
return result;
...
double[]toDoubles(byte[] value, int offset, int num)
to Doubles 
double[] values = new double[num];
int idx = 0;
for (int i = offset; i < offset + (num * 8); i += 8) {
    values[idx++] = getDouble(value, i);
return values;
double[]toDoubles(Double[] values)
to Doubles 
return toDoubles(values, DEFAULT_DOUBLE);
double[][]toDoubles(int[][] intPts)
to Doubles 
int nDimensions = intPts[0].length;
double[][] pts = new double[intPts.length][nDimensions];
for (int i = 0; i < intPts.length; i++) {
    for (int n = 0; n < nDimensions; n++) {
        pts[i][n] = ((Integer) intPts[i][n]).doubleValue();
return pts;
...
double[]toDoubles(Object[] extraArgs)
to Doubles 
double[] ret = new double[extraArgs.length];
for (int i = 0; i < extraArgs.length; i++) {
    ret[i] = Double.valueOf(extraArgs[i].toString());
return ret;
doubletoDoubleScore(Float score)
This is from mneme Convert the points / score value into a double, without picking up float to double conversion junk 
if (score == null)
    return 0.0d;
float times100 = score.floatValue() * 100f;
Double rv = (double) times100;
rv = rv / 100d;
return rv;
StringtoDoubleString(Double d)
Formats the specified double as string 
if (d == null) {
    return ZERO_STRING;
return d.toString();
doubletoDoubleValue(Object number)
Returns the number object as a double 
if (number instanceof Double) {
    return ((Double) number).doubleValue();
if (number instanceof Float) {
    return ((Float) number).doubleValue();
if (number instanceof Long) {
    return ((Long) number).doubleValue();
...
DoubletoDoubleValue(Object value)
to Double Value 
if ((value == null) || (value.getClass() == Double.class)) {
    return (Double) value;
if (value instanceof Number) {
    return ((Number) value).doubleValue();
throw new IllegalArgumentException("value must be instance of Number.");
