Andrew Miller <[EMAIL PROTECTED]> has asked for Include_in_CellML_1.2: Tracker Item 84: Locale differences for real number formats http://bowmore.elyt.com/bugzilla/show_bug.cgi?id=84
------- Additional Comments from Andrew Miller <[EMAIL PROTECTED]> The CellML Specification says that several different attributes must be real numbers, but doesn't specify the format in which these real numbers are expressed. The common computer formats for representing real numbers in text differ from locale to locale, and so a valid real number in one locale may be invalid in another, therefore harming the interoperability of CellML models. I propose that we provide a basic specification of allowable real number representations in text for use in attributes such as exponent, initial_value, and so on. MathML 2.0 already deals with this through the following text: "The cn element is used to specify actual numerical constants. The content model must provide sufficient information that a number may be entered as data into a computational system. By default, it represents a signed real number in base 10. Thus, the content normally consists of PCDATA restricted to a sign, a string of decimal digits and possibly a decimal point, or alternatively one of the predefined symbolic constants such as π". _______________________________________________ cellml-discussion mailing list [email protected] http://www.cellml.org/mailman/listinfo/cellml-discussion
