3DNow! was designed to be the natural evolution of MMX from integers to floating point.
A 64-bit float is sometimes called a "real64" or a "double", meaning "double-precision floating-point value".
A floating-point system can be used to represent, with a fixed number of digits, numbers of different orders of magnitude : e.g. the distance between galaxies or the diameter of an atomic nucleus can be expressed with the same unit of length.
A floating-point co-processor was also available, taking up a separate slot.
Alternatives to floating-point numbers The floating-point representation is by far the most common way of representing in computers an approximation to real numbers.
All registers are accessed through standard ARM architecture coprocessor mapping mechanism. iwMMXt occupies coprocessors 0 and 1 space, and some of its opcodes clash with the opcodes of the earlier floating-point extension, FPA.
