Floating point arithmetic algorithm
WebFloating-point arithmetic is considered as esoteric subject by many people. This is rather surprising, because floating-point is ubiquitous in computer systems: Almost every … In computing, floating-point arithmetic (FP) is arithmetic that represents real numbers approximately, using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. For example, 12.345 can be represented as a base-ten floating-point number: In … See more Floating-point numbers A number representation specifies some way of encoding a number, usually as a string of digits. There are several mechanisms by which strings of digits can … See more The IEEE standardized the computer representation for binary floating-point numbers in IEEE 754 (a.k.a. IEC 60559) in 1985. This first standard is followed by almost all modern … See more By their nature, all numbers expressed in floating-point format are rational numbers with a terminating expansion in the relevant base (for … See more Floating-point computation in a computer can run into three kinds of problems: • An operation can be mathematically undefined, such as ∞/∞, or division by zero.
