Expression Langauge

Integral Types

• integer
• double
• mesh variables: strings, e.g. "pressure" indicate a variable defined on the mesh.
• bool: Note: only produced as the result of a comparison. Not sure we need keywords true and false since I don't see how we would use it in practice.

Binary Operators

• Math: -, +, *, /, %
• Comparison: ==, >=, <=, !=, >, <
• Boolean: not implemented. We had the goal of being python like so maybe these should be and, or , and not, as opposed to &&, ||, and !. For JIT, we can just substitute whatever we need back in. Note: not is a unary operator.

Unary Operators

• -
