EOS (Equation Operating System)
Hierarchy
Exponentiation (^) and element-by-element
exponentiation (.^) are evaluated from right to
left, for example, 2^3^4 = 2^(3^4).
Post operations and exponentiation are
performed before negation, for example, -9^2 =
-(9^2).
Other operations are performed according the
these priorities:
1 Parentheses (), brackets [] and braces {}
2 Indirection (#)
3 Function calls
4 Post operators: degrees-minutes-seconds
(°,',"), factorial (!), percentage (%),
radian (), transpose ()
5 Exponentiation, power operator (^)
6 Negation (-)
7 String concatenation (&)
8 Multiplication (*), division (/)
9 Addition (+), subtraction (-)
10 Equality relations: =, ≠, <, ≤, >, ≥
11 Logical 'not'
12 Logical 'and'
13 Logical 'or', 'xor'
14 Constraint "with" operator (|)
15 Store (→)
