The IEEE Standard for Floating-Point Arithmetic (IEEE 754) is a technical standard for floating-point arithmetic established in 1985 by the Institute of Electrical and Electronics Engineers (IEEE). The standard addressed many problems found in the diverse floating-point implementations that made them difficult … See more The first standard for floating-point arithmetic, IEEE 754-1985, was published in 1985. It covered only binary floating-point arithmetic. A new version, IEEE 754-2008, was published in August … See more The standard defines five rounding rules. The first two rules round to a nearest value; the others are called directed roundings See more The standard defines five exceptions, each of which returns a default value and has a corresponding status flag that is raised when the exception occurs. No other exception … See more Signed zero In the IEEE 754 standard, zero is signed, meaning that there exist both a "positive zero" (+0) and a … See more An IEEE 754 format is a "set of representations of numerical values and symbols".
