```
throw new IllegalArgumentException("Input data is longer than size of
'double' primitive ("+SIZE+" bytes)");
```
tips:
next time when you wanna bake some codes from a template for all primitive
types, suggest use `boolean`, as boolean is the less troublesome one in them...
if cannot use `boolean` then can use `double`
do never use `int` or `long` as template...that will cause the
`longer->doubleer` thing.

> Hello,
> I need a set of methods to convert Long to or from a byte[] array, as if
> writing / reading from Data(Input/Output)Stream(
> ByteArray(Input/Output)Stream ).
> First, doing it with Streams seems a bit wasteful, second, it seems a
> pretty general use. Would it be possible to add something like that to,
> for example,
> org.apache.commons.lang.math.NumberUtils?
> Example code:
> {code:java}
> static public long toLong(byte[] b)
> {
> return toLong(b, 0);
> }
>
> static public long toLong(byte[] b, int offset)
> {
> return (((long)b[offset] << 56) +
> ((long)(b[offset + 1] & 255) << 48) +
> ((long)(b[offset + 2] & 255) << 40) +
> ((long)(b[offset + 3] & 255) << 32) +
> ((long)(b[offset + 4] & 255) << 24) +
> ((b[offset + 5] & 255) << 16) +
> ((b[offset + 6] & 255) << 8) +
> ((b[offset + 7] & 255) << 0));
> }
>
> static public byte[] longToByteArray(long l)
> {
> byte b[] = new byte[8];
> longToByteArray(l, b, 0);
> return b;
> }
>
> static public void longToByteArray(long l, byte b[], int offset)
> {
> b[offset] = (byte)(l >>> 56);
> b[offset + 1] = (byte)(l >>> 48);
> b[offset + 2] = (byte)(l >>> 40);
> b[offset + 3] = (byte)(l >>> 32);
> b[offset + 4] = (byte)(l >>> 24);
> b[offset + 5] = (byte)(l >>> 16);
> b[offset + 6] = (byte)(l >>> 8);
> b[offset + 7] = (byte)(l >>> 0);
> }
> {code}
