Examples of JexlArithmetic

org.apache.commons.jexl2.JexlArithmetic

Perform arithmetic.

All arithmetic operators (+, - , *, /, %) follow the same rules regarding their arguments.

If both are null, result is 0
If either is a floating point number, coerce both to Double and perform operation
If both are BigInteger, treat as BigInteger and perform operation
If either is a BigDecimal, coerce both to BigDecimal and and perform operation
Else treat as BigInteger, perform operation and attempt to narrow result:
1. if both arguments can be narrowed to Integer, narrow result to Integer
2. if both arguments can be narrowed to Long, narrow result to Long
3. Else return result as BigInteger
