Java Utililty Methods Double Array to Byte Array

byte[] doublesToBytes(double[] d)
doubles To Bytes

byte[] b = new byte[d.length << 3];
for (int i = 0; i < d.length; i++) {
 copyLongIntoByteArray(b, i << 3, Double.doubleToRawLongBits(d[i]));
return b;

byte[] doublesToBytes(double[] doubles)
Converts an array of doubles into an array of bytes Byte order: little endian

long[] longs = new long[doubles.length];
for (int i = 0; i < doubles.length; i++) {
 longs[i] = Double.doubleToLongBits(doubles[i]);
return longsToBytes(longs);

byte[] doublesToBytes(final double[] array)
convert an array of double values to an array of byte .

final byte[] res;
int i;
res = new byte[array.length];
i = 0;
for (final double x : array) {
 res[i++] = ((byte) x);
return res;
