Intel® C++ Compiler 16.0 User and Reference Guide
This version of the compiler uses a close approximation to the IEEE Standard for Floating-Point Arithmetic, IEEE 754™-2008, unless otherwise stated. This standard is common to many microcomputer-based systems due to the availability of fast processors that implement the required characteristics.
This section outlines the characteristics of the standard and its implementation in the compiler. Except as noted, the description refers to both the IEEE standard and the compiler implementation.
