Floating point
In computing, floating point describes a method of representing real numbers in a way that can support a wide range of values. Numbers are, in general, represented approximately to a fixed number of significant digits and scaled using an exponent. The base for the scaling is normally 2, 10 or 16...

In geometry, the tesseract, also called an 8-cell or regular octachoron or cubic prism, is the four-dimensional analog of the cube. The tesseract is to the cube as the cube is to the square. Just as the surface of the cube consists of 6 square faces, the hypersurface of the tesseract consists of 8...

". Unfortunately, parallel processing was still in its infancy and the tools and libraries for the T-Series did not make it easy for customers to get the full potential of the parallel architecture. I/O was also a difficulty and the T-Series was discontinued, a mistake costing tens of millions of dollars that was nearly fatal to FPS.
