In 1963, Digital announced the PDP-6, which had floating point as a standard feature. This was carried forward to its successors the 709, 7090, and 7094. ![]() In 1954, the IBM 704 had floating-point arithmetic as a standard feature, one of its major improvements over its predecessor the IBM 701. A floating-point unit emulator (a floating-point library).When a CPU is executing a program that calls for a floating-point operation, there are three ways to carry it out: In general-purpose computer architectures, one or more FPUs may be integrated as execution units within the central processing unit however, many embedded processors do not have hardware support for floating-point operations (while they increasingly have them as standard, at least 32-bit ones). Some FPUs can also perform various transcendental functions such as exponential or trigonometric calculations, but the accuracy can be very low, so that some systems prefer to compute these functions in software. Typical operations are addition, subtraction, multiplication, division, and square root. Collection of the x87 family of math coprocessors by IntelĪ floating-point unit ( FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers.
