The copyright holder grants you permission to redistribute this document freely as a verbatim copy. Furthermore, the copyright holder permits you to develop any derived work from this document provided that the following conditions are met. a) The derived work acknowledges the fact that it is derived from this document, and maintains a prominent reference in the work to the original source. b) The fact that the derived work is not the original OpenMath document is stated prominently in the derived work. Moreover if both this document and the derived work are Content Dictionaries then the derived work must include a different CDName element, chosen so that it cannot be confused with any works adopted by the OpenMath Society. In particular, if there is a Content Dictionary Group whose name is, for example, `math' containing Content Dictionaries named `math1', `math2' etc., then you should not name a derived Content Dictionary `mathN' where N is an integer. However you are free to name it `private_mathN' or some such. This is because the names `mathN' may be used by the OpenMath Society for future extensions. c) The derived work is distributed under terms that allow the compilation of derived works, but keep paragraphs a) and b) intact. The simplest way to do this is to distribute the derived work under the OpenMath license, but this is not a requirement. If you have questions about this license please contact the OpenMath society at http://www.openmath.org. relation1 http://www.openmath.org/cd http://www.openmath.org/cd/relation1.ocd 2006-03-30 2004-03-30 3 0 official This CD holds the common arithmetic relations. It is intended to be `compatible' with the appropriate MathML elements. eq application This symbol represents the binary equality function. a=b and b=c implies a=c An example which represents the statement 1 + 2 = 3. 1 2 3 lt application This symbol represents the binary less than function which returns true if the first argument is less than the second, it returns false otherwise. a<b and b<c implies a<c An example which represents the statement 1 + 2 < 4 1 2 4 gt application This symbol represents the binary greater than function which returns true if the first argument is greater than the second, it returns false otherwise. a>b and b>c implies a>c An example which represents the statement 1 + 2 > 2 1 2 2 neq application This symbol represents the binary inequality function. it is not true that a=/b and b=/c implies a=/c An example which represents the statement 1 + 2 not = 2 1 2 2 leq application This symbol represents the binary less than or equal to function which returns true if the first argument is less than or equal to the second, it returns false otherwise. a<=b and b<=c implies a<=c An example which represents the statement 1 + 2 <= 4 1 2 4 geq application This symbol represents the binary greater than or equal to function which returns true if the first argument is greater than or equal to the second, it returns false otherwise. a>=b and b>=c implies a>=c An example which represents the statement 1 + 2 >= 3 1 2 3 approx application This symbol is used to denote the approximate equality of its two arguments. \pi is approximately 355/113 355 113
