The ExprTk expression evaluator supports the following fundamental
arithmetic operations, functions and processes:
- Types:
- Scalar, Vector, String
- Basic operators:
+, -, *, /, %, ^
- Assignment:
:=, +=, -=, *=, /=, %=
- Equalities & Inequalities:
=, ==, <>, !=, <, <=, >, >=
- Logic operators:
- and, mand, mor, nand, nor, not, or, shl, shr,
xnor, xor, true, false
- Functions:
- abs, avg, ceil, clamp, equal, erf, erfc, exp,
expm1, floor, frac, log, log10, log1p, log2,
logn, max, min, mul, ncdf, nequal, root,
round, roundn, sgn, sqrt, sum, swap, trunc
- Trigonometry:
- acos, acosh, asin, asinh, atan, atanh, atan2,
cos, cosh, cot, csc, sec, sin, sinc, sinh,
tan, tanh, hypot, rad2deg, deg2grad, deg2rad,
grad2deg
- Control structures:
- if-then-else, ternary conditional, switch-case,
return-statement
- Loop statements:
- while, for, repeat-until, break, continue
- String processing:
- in, like, ilike, concatenation
- Optimisations:
- constant-folding, simple strength reduction and
dead code elimination
- Calculus:
- numerical integration and differentiation
