Method

DoublefloatToDouble(final float value)
float To Double 
return (double) value;
doublefloatToDouble(float converThisNumberToFloat)
float To Double 
String floatNumberInString = String.valueOf(converThisNumberToFloat);
double floatNumberInDouble = Double.parseDouble(floatNumberInString);
return floatNumberInDouble;
double[]floatToDouble(float[] array)
Convert a float array to a double array. 
double[] darr = new double[array.length];
for (int i = 0; i < array.length; i++) {
    darr[i] = array[i];
return darr;
double[]floatToDouble(float[] values)
float To Double 
if (values == null) {
    return null;
double[] results = new double[values.length];
for (int i = 0; i < values.length; i++) {
    results[i] = values[i];
return results;

double[]floatToDoubleArray(float[] arr)
float To Double Array 
double[] ret = new double[arr.length];
for (int i = 0; i < arr.length; i++) {
    ret[i] = new Float(arr[i]).doubleValue();
return ret;
doublefloatToDoubleLower(float f)
Return the largest double that rounds up to this float. 
if (Float.isNaN(f)) {
    return Double.NaN;
if (Float.isInfinite(f)) {
    if (f < 0) {
        return Double.NEGATIVE_INFINITY;
    } else {
