<dl>
<dd> Convert a byte into an hexadecimal number. The output is always lowercase, two digit long in the range <code>00-ff</code>. <p><b>Example:</b> <code>12</code> gives <code>0c</code>, <code>18</code> gives <code>12</code>, <code>255</code> gives <code>ff</code>, ...

<dl>
<dd> Convert a number represented by the given byte array into a hexadecimal number String. <p><b>Example:</b> <code>{ 12, 22, 16 }</code> gives <code>0c1610</code>. That means <code>12</code> is <code>0c</code>, <code>22</code> is <code>16</code>, <code>16</code> is <code>10</code> or, if you prefer all together,<br> <code>12 * 256^2 + 22 * 256^1 + 16 * 256 = 792080</code> gives <code>c1610</code>.
