All decimal, float, and double numbers are compressed to an integer when represented, if there are only zeros following the decimal point (for example, "1.000" is represented as
1). Scientific notation is never used to represent a floating point number as a string (for example, "
xs:double(’1.234E05’)" is represented as
123400). Data is truncated if the number of digits exceeds the maximum precision for the datatype (for example, "
xs:float(’1.23456789’)" is represented as
1.2345679).
Both zero and negative zero are represented as 0. Positive and negative infinity are represented as
Infinity and
-Infinity. Not a number is represented as
NaN.
xs:boolean(’true’) and
xs:boolean(’1’) are represented by true. The XPath function
true() is also represented as
true.
TIBCO BusinessEvents Function Argument Wizard (also known as the function argument mapper) implements dates in one of two ways. Either a date is stored as the number of milliseconds since January 1, 1970, or the date is implemented according to the XPath 2.0 or XQuery 1.0 standards as a set of normalized components (xs:date,
xs:time,
xs:dateTime, and so on) with an optional time zone offset. Activities that are associated with Java (for example, Java Code, Java Method, and so on) use the first implementation. Activities that are associated with XML (for example, Mapper, Parse XML, and so on) use the second implementation. The second implementation supports arbitrary precision of the seconds component.
