Information Technology. Programming languages, their environments, and system software interfaces. Floating-point extensions for C. Decimal floating-point arithmetic | Status: Revised, Superseded, Withdrawn

1 Scope This part of ISO/IEC/TS 18661 extends programming language C as specified in ISO/IEC 9899:2011, (C11) with changes specified in ISO/IEC/TS 18661-1, to support decimal floating-point arithmetic conforming to ISO/IEC/IEEE 60559:2011. It covers all requirements of IEC 60559 as they pertain to C decimal floating types. This part of ISO/IEC/TS 18661 supersedes ISO/IEC/TR 24732:2009. This part of ISO/IEC/TS 18661 does not cover binary floating-point arithmetic (which is covered in ISO/IEC/TS 18661-1), nor does it cover most optional features of IEC 60559.
