I would like to know whether tag 118 (Net money) will support an exponential form or not in a ticketing message (FIX 4.0)?

Always willing to help out someone from the parent company 
The FIX.4.0 specification lists tag 118 as type float.
The specification also has this to say about any field of type float:
float: Sequence of digits with optional decimal point and sign character (ASCII characters “-”, “0” - “9” and “.”); the absence of the decimal point within the string will be interpreted as the float representation of an integer value. All float fields must accommodate up to fifteen significant digits.
I therefore must conclude that any characters such as ‘E’, ‘e’ or ‘*’ are invalid which would rule out all ASCII representations of exponents that I have ever seen.
