in j806, 9999999999999999.310000000000000000 probably the j805 behaviour is
preferred. If only for consistency. But there may be a good reason for
change.

Subject: [Jprogramming] Integer-floating type change for large numbers in j805
and j806
I am guessing that the following has something to do with precision of large
numbers in j805 and is also true for j806.

Further investigation shows me it was not this way with the 32 bit version of
j701, so it may be an artifact of moving to 64 bit?
