Simple WebGL2 HALF_FLOAT texture test to increase x2 GPU bandwidth (see the page source). We need half-precision floating point for JavaScript too. See also Float16Array discussion.

Note, that with "#precision mediump" You can get x2 f16 Math acceleration too on modern Intel (SkyLake), mobile and Nvinia GPU (NVIDIA Turing Architecture In-Depth).

See also Matrix multiplication in Compute shaders.
