This package provides IEEE 754 compliant functions for converting to and from half-precision, 16-bit, floating point numbers. It properly handles NaNs, infinities, and subnormal numbers.
###Purpose
This package is primarily intended for use with OpenGL. By specifying vertexes or textures as 16-bit floats, you can save video memory, improve buffer upload times, and draw faster. Besides OpenGL, 16-bit floats are also used in many image formats, such as OpenEXR, for high dynamic range and deep color.
###Limitations The range and precision of a 16-bit float are much less than a 32-bit float. They can represent positive and negative values as small as 0.000062 and as large as 65504.0 with approximately 3 decimal digits of precision. For example, pi is rounded to 3.140625.
###Credit The conversion functions are based on a Stack Overflow post by Paul "Phernost" Tessier: http://stackoverflow.com/questions/1659440/32-bit-to-16-bit-floating-point-conversion
