| Abstract | This paper incorporates some of the discussions by the ACM/SIGAda Working Group on Ada Numerics, the ISO/TC97/SC22/WG9 Rapporteur Group on an elementary functions package, and the Ada-Europe Ada Numerics Working Group. This is not a report from any one of those groups nor does it attempt to reflect all the discussions or potential resolutions of the issues. This paper is the author's attempt to provide information on the current thinking of these groups about a standard specification for an elementary functions package for Ada so that a broader group can assess the utility and trade-offs involved in such standard specifications and libraries.The following people have been involved in developing and influencing the ideas presented here: Jim Cody, Paul Cohen, Sandy Cohen, Ken Dritz, Brian Ford, Graham Hodgson, Jan Kok, Gil Myers, Brian Smith, Jon Squire, and Bill Whitaker. Any confusion or inaccuracies are the author's. These people represent a combination of interests in the Ada language ranging from numerical analysis to embedded application development.The SIGAda Numerics Working Group (SIGAda NUMWG) has met at the SIGAda meetings in Pittsburgh, PA (July, 1986), Charleston, WV (November, 1986), Fort Lauderdale, FL (January, 1987), and Seattle, WA (August, 1987), several times at Argonne National Laboratory near Chicago, IL and at various locations in the Washington, DC area. The Numerics Working Group of Ada-Europe has met many times on this and related topics.A number of proposals for elementary functions in Ada ([FIRTH 1982], [WHITAKER & EICHOLTZ 1982], [WITTE 1983], [SYMM, WICHMANN, KOK & WINTER 1984], [KOK & SYMM 1984], and [KOK 1987]) have been studied by the SIGAda NUMWG. These were considered along with recent work in numerical analysis about the calculation of the elementary functions and about the properties of floating point arithmetic. Various aspects of Ada's real arithmetic, type mechanism, generic packages, and library structures have also been considered as they relate to the specification and implementations of a potentially widely used package.The proposed package specification is given at the very end of the paper as a convenient reference point. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
