Method

doubletoDouble(final Object obj)
to Double 
try {
    if (obj instanceof String) {
        return Double.valueOf((String) obj).doubleValue();
    } else if (obj instanceof Number) {
        return ((Number) obj).doubleValue();
    } else {
        throw new IllegalArgumentException("Could not convert value to number: " + obj);
} catch (Exception e) {
    throw new IllegalArgumentException("Could not convert value to number: " + obj, e);
doubletoDouble(final Object value)
To double. 
if (value == null) {
    return 0;
return new Double(value.toString());
DoubletoDouble(final Object valueRep)
to Double 
return Double.parseDouble(String.valueOf(valueRep));
doubletoDouble(final String argStr)
to Double 
double ret = Double.NaN;
try {
    ret = Double.valueOf(argStr);
} catch (NumberFormatException nfE) {
return ret;
DoubletoDouble(final String value)
Converts a String to a double plus if the String is NULL, the returned value will be NULL. 
if (value == null) {
    return null;
return Double.valueOf(value);
doubletoDouble(final String value)
To double. 
if (value == null) {
    return 0.0D;
String szTemp = "";
for (int i = 0; i < value.length(); i++)
    if (value.charAt(i) != ',') {
        szTemp = szTemp + value.charAt(i);
try {
    final double d = Double.parseDouble(szTemp);
    return d;
} catch (final NumberFormatException e) {
    final double d1 = 0.0D;
    return d1;

double[] b = new double[a.length];
for (int i = 0; i < a.length; i++)
    b[i] = a[i];
return b;
double[]toDouble(float[] a)

double[] re = new double[a.length];
for (int i = 0; i < re.length; i++)
    re[i] = (double) a[i];
return re;
double[]toDouble(float[] array)
to Double 
int n = array.length;
double[] a2 = new double[n];
for (int i = 0; i < n; i++) {
    a2[i] = array[i];
return a2;
