Pretty sure that "e+21" at the end there means that the field ran out of space. It's a shorthand way of writing huge numbers, like scientific notation. I'm not gonna use that long ass number for examples because it sucks, so...
You could have a largeish number, like 1,234,000
With scientific notation, that number could be written as 1.234X10^6. You could actually calculate that, or just move the decimal 6 places over, and the number becomes 1,234,000 again. The "e+n" is telling you the same thing, so 1,234,000 could be written as 1.234e+6.
