http://nagoya.apache.org/bugzilla/show_bug.cgi?id=9059 Results of calculations on floating numbers are rounded to 6 decimal digits Summary: Results of calculations on floating numbers are rounded to 6 decimal digits Product: XalanC Version: 1.3.x Platform: All OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: XalanC AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] With Xalan C 1.3 (I don't know if it's true before), calculations (including simple additions) on floating numbers are rounded to 6 decimal digits, even if one of the operands has more than 6 decimal digits. After having looked at the source files, I think the problem could be located in the file ./PlatformSupport/DOMStringHelper.cpp and the function XalanDOMString& DoubleToDOMString(double theDouble, XalanDOMString& theResult) at the sentence (line 1506 of 1750): unsigned int theCharsWritten = sprintf(theBuffer, "%f", theDouble); Applying such a format to a double indeed rounds it to 6 decimal digits, at least on solaris and linux (and, I bet, with a number of other compilers, as it should be the behavior of the ansi C printf() function). I don't have a clear idea of what to do, but in my opinion, this should be improved. Note: we don't have this problem with Xalan J.
