The MathExpr expression evaluator supports the following fundamental arithmetic operations, functions and processes:

1. Types: Scalar, Vector, String

2. Basic operators: +, -, *, /, %, ^

3. Assignment: :=, +=, -=, *=, /=, %=

4. Equalities & Inequalities: =, ==, !=, <, <=, >, >=

5. Logic operators: and, mand, mor, nand, nor, not, or, shl, shr, xnor, xor, true, false

6. Functions: abs, avg, ceil, clamp, equal, erf, erfc, exp, expm1, floor, frac, log, log10, log1p, log2, logn, max, min, mul, ncdf, not_equal, root, round, roundn, sgn, sqrt, sum, swap, trunc

7. Trigonometry: acos, acosh, asin, asinh, atan, atanh, atan2, cos, cosh, cot, csc, sec, sin, sinc, sinh, tan, tanh, hypot, rad2deg, deg2grad, deg2rad, grad2deg

8. Control structures: if-then-else, ternary conditional, switch-case, return-statement

9. Loop statements: while, for, repeat-until, break, continue

10. String processing: in, like, ilike, concatenation

11. Optimisations: constant-folding, simple strength reduction and dead code elimination

12. Runtime checks: vector bounds, string bounds, loop iteration, execution-time bounds and compilation process checkpointing, assert statements

13. Calculus: numerical integration and differentiation
