In addition to the . and [] operators discussed in Variables, EL expressions provide the following operators:

Arithmetic: +, - (binary), *, / and div, % and mod, - (unary)
Logical: and, &&, or, ||, not, !
Relational: ==, eq, !=, ne, <, lt, >, gt, <=, ge, >=, le. Comparisons can be made against other values, or against boolean, string, integer, or floating point literals.
Empty: The empty operator is a prefix operation that can be used to determine whether a value is null or empty.
Conditional: A ? B : C. Evaluate B or C, depending on the result of the evaluation of A.

The precedence of operators highest to lowest, left to right is as follows:
