Abstract

Describes constraints on parameters defining values of basic and extended floating-point numbers, add, subtract, multiply, divide, square, root, remainder and compare operations, conversions between integers and floating-point numbers, conversions between different floating-point precisions, conversion between basic precision floating-point numbers and decimal strings and floating-point exceptions and their handling including non-numbers.
