Method

byte[]doubleToByteArray(double value)
double To Byte Array 
return longToByteArray(Double.doubleToRawLongBits(value));
byte[]doubleToByteArrayBE(double data)
Convert a double to a byte array (big endian). 
return longToByteArrayBE(Double.doubleToRawLongBits(data));
byte[]doubleToBytes(double d)
This function converts a double to its corresponding byte array format. 
byte[] buffer = new byte[8];
doubleToBytes(d, buffer, 0);
return buffer;
byte[]doubleToBytes(double d)
double To Bytes 
long l = Double.doubleToRawLongBits(d);
byte[] r = new byte[8];
for (int i = 0; i < 8; i++) {
    r[i] = (byte) ((l >>> (i * 8)) & 0xFF);
return r;
byte[]doubleToBytes(double d)
double To Bytes 
return longToBytes(Double.doubleToLongBits(d));
byte[]doubleToBytes(double d, byte[] bytes, int off, boolean bigEndian)
double To Bytes 
return bigEndian ? doubleToBytesBE(d, bytes, off) : doubleToBytesLE(d, bytes, off);
voiddoubleToBytes(double d, byte[] data, int[] offset)
Write the bytes representing d into the byte array data, starting at index offset [0], and increment offset [0] by the number of bytes written; if data == null, increment offset [0] by the number of bytes that would have been written otherwise. 
long bits = Double.doubleToLongBits(d);
longToBytes(bits, data, offset);
intdoubleToBytes(double dnum, byte[] bytes, int startIndex)
Given a double, convert it into a byte array 
return longToBytes(Double.doubleToLongBits(dnum), bytes, startIndex);
voiddoubleToBytes(double v, byte[] bytes)
double To Bytes 
doubleToBytes(v, bytes, 0);
voiddoubleToBytes(double v, byte[] bytes, int off)
double To Bytes 
long el = Double.doubleToRawLongBits(v);
int shift = 64;
int lim = off + 8;
for (int i = off; i < lim; i++) {
    shift -= 8;
    bytes[i] = (byte) ((el >> shift) & 0xFF);
