> In JexlArithmetic.java method *public BigInteger toBigInteger(Object val)* uses the following
case for BigDecimals as for any other numbers:
> ...
>  else if (val instanceof Number) {
>             return BigInteger.valueOf(((Number) val).longValue());
> ...
> For large BigDecimals > Long.MAX_VALUE it may lead to loss of value. Please consider
using BigDecimal.toBigInteger() method for that case?
