EXPRESS — EXPRESS MM issue: Correct definition of E

Clause 9.8.2 I don't know what the "Napierian exponential function" is. Perhaps it is more usual to native English speaker? Yet I didn't find anything worthwhile when I googlized it (is Google anyway a reference?). I just know the "exponential function" and the "naperian logarithm function" which is the inverse of the preceding.
Yet defining e from one of these functions whose definitions are, AFAIK, based on e itself doesn't make sense.
I'd recommand to use the original Euler's definition: see http://en.wikipedia.org/wiki/E_(mathematical_constant)#History
If agreed, that could be handled through an issue for the 2nd FTF.

The definition of E in the specification was taken verbatim from ISO 10303-11 Clause 14.2. However, the issue is correct: Napier published a table of natural logarithms, but the exponential function is credited to Euler. The specification should use one of Euler's definition (based on the area under the curve 1/x), or Bernoulli's definition (the limit of (1+1/n)n).
