Class EnsureDenominatorIsTypeDouble
For any BinaryOperation with Divide, apply Mangrove.MetricSetTransformers.Internal.Arithmetic.EnsureTypeDouble(Mangrove.MetricSetSyntaxTree.Expression) to the denominator. Mangrove makes the assumption that number division is non-integer, so for any a/b with a and b both integer, we need to explicitly cast b to type double.
For example, if a literal is of type double but the value is specified as "1", in the generated script it would simply be "1", and so for example if the script has a division 1/SUM(integer value), this division will be incorrectly treated as INTEGER division and NOT DOUBLE division, which would result in the value 0.
