The first argument of the XSLT format-number function is required to be a 
number.  According to Section 3.5 of XPath 1.0 [1], a number is an IEEE 754 
double-precision, 64-bit format value.  The limits on the precision of such a 
value are approximately 16 decimal digits.  The differences you see between the 
input values and the formatted output values are due to the loss of precision 
inherent in representing the value as a floating-point number.
