MalformedAlgebraicExpressionException class
An exception thrown by DartBlock when calculating the value of a DartBlockAlgebraicExpression.
Cases include:
- division by zero.
- the use of the module (%) operator with a negative right operand.
- a missing operator when both the left and right operand are non-null.
- the left operand and right operand both being null.
- the left operand, the right operand and the operator all being null.
- the left operand being null, the right operand being non-null and the operator being either '*', '/' or '%'.
See DartBlockValueTreeAlgebraicOperatorNode.getValue for the implementation details.
