It's widely used to improve performance and memory impact, which is of particular importance on mobiles. The format interacts with the host space when during vertex data upload, texture data upload, uniform data upload, transform & feedback readback and texture data readback. > The current spec is based on IEEE 754 and matches the floating point > specs.
