> Currently the math operations in Expression Language use Longs to evaluate numbers. This leads to any decimal places getting truncated when performing operations like divide. 
> EL should be improved to enable the user to evaluate math expressions using doubles.
> Another desired portion of this would be to open up the static Math class [1] methods (using reflection) to further enable working with Decimals.
