Use MATLAB to convert a scalar double into a half-precision floating point. The return value should be a uint16.

The half-precision floating point format is specified here, and is the source for much of the test suite:

http://en.wikipedia.org/wiki/Half-precision_floating-point_format

This is an implementation in C if you want some inspiration to get started:

As other problems related to half-precision are added, I will try to link them here.

The only thing missing from the test suite are nans,regardless, it's a very good problem. Learned how to extract minus from minus 0, and finally took my time to learn about the controversial denormal floating-points numbers.
