Why is there no 2 byte float and does an implementation already exist?
<p>Assuming I am really pressed for memory and want a smaller range (similar to short vs int). Shader languages already support <code>half</code> for a floating point with half the precision (not just convert back and forth for the value to be between -1 and 1, that is, return a float like this: <code>shortComingIn / maxRangeOfShort</code>). Is there an implementation that already exists for a 2 byte float?</p>

<p>I am also interested to know any (historical?) reasons as to why there is no 2 byte float.</p>
