If 'float' or 'round' throw an exception, the assignment to 'val' never
happens, so 'val' is undefined. Try examining the value of 'decval' in
the debugger to see what is making the conversion fail.
That's exactly what the OP did :) Trouble is, it didn't help, because
it sure looked as if decval was the string '4'. My best guess was -
and is - that it's not just a string. We're looking at an SQL
interface routine here, so it may be that there's a string subclass
that length-limits itself, on the assumption that it's going into a
fixed-length database field.
It ran almost to completion before generating the error again --
(Pdb) decval
'4'
(Pdb) type(decval)
<type 'str'>
(Pdb) len(decval)
1
(Pdb) int(decval)
*** ValueError: invalid literal for int() with base 10: '41.700000000000003'
So there's still something amiss.
