It displays '3E+1' instead of '30.0'.
As I can't reproduce I'm looking for an idea brainstorm of what could be causing
this. What would be choosing to display such a normal number in scientific
notation?
Ideas?

LOL!
I suspect it's your use of the Decimal normalize() method that's
causing
this. Trailing zeros on Decimal instances are significant, so
Decimal('30.0'), Decimal('30') and Decimal('3E+1') are considered
distinct (though they all have the same value). The normalize method
strips all trailing zeros, turning Decimal('30.0') into Decimal('3E
+1').
One way to get around this is to add 0 after normalizing: this will
make sure that scientific notation is used only for very large
or small numbers, as usual.
Thank you for the insight. I believe the problem is with my use of normalize(), but I
still can't figure out why I can't reproduce the issue in my running app. But I can
see in the interpreter that printing Decimal("30.0").normalize() results in "3E+1".
