Is it like <assign ... expr="'1234567891'" /> or <assign ... expr="1234567891"
/>?
The former is handed as a string, but the latter is handled as a number.

If it was passed as string, then you could use new
BigDecimal(lastParams.get("A")).
But, I guess you got a numeric object from lastParams.get("A") instead.

Expressions are evaluated by an Evaluator. If you're using JexlEvaluator, then
you can refer to this:
- http://commons.apache.org/proper/commons-jexl/reference/syntax.html
I think you can treat it as a string with single quotes or as a number with a
suffix (e.g, 1234567891B or 1234567891.0H).
