Has anyone read the FAST specification recently and noticed some strange 
discrepancies in the examples? Maybe I'm lacking some sleep, but, I believe 
that the tables are inconsistent in the way that they present the encoded data.

For an example of what is confusing me, consider example 3 of Appendix 3.2.4.

For the first row, the Encoded Value is set to "N/A-N/A", so how does the 
receiver deduce that the second value should be 12100? Admittedly, I have only 
read through the specification once but the way that I read it, a transmitted 
value of 0xff 0xed is required to get from 12000 to 12100? I didn't notice 
anything in the spec that confirms whether the receiver preloads the prior 
value as 0 or as 12000 for this case, but I assume that it starts at 12000,

Also, why does the third line use a mantissa of 1210 and an exponent of 1 and 
not 2/121?

Please help a very confused newbie!
