In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities. These include numerical equality ( e.g. , 5 = 5 ) and inequalities ( e.g. , 4 ≥ 3 ).
APL uses the term operator in Heaviside’s sense as a moderator of a function as opposed to some other programming language's use of the same term as something that operates on data, ref. relational operator and operators generally. Other programming languages also sometimes use this term interchangeably with function, however both terms are ...
Scratch 3.0 only supports one-dimensional arrays, known as "lists", and floating-point scalars and strings are supported but with limited string manipulation ability. There is a strong contrast between the powerful multimedia functions and multi-threaded programming style and the rather limited scope of the Scratch programming language.
miniKanren is a family of programming languages for relational programming. [1] As relations are bidirectional, if miniKanren is given an expression and a desired output, miniKanren can run the expression "backward", finding all possible inputs to the expression that produce the desired output. This bidirectional behavior allows the user to ...

The operator precedence is a number (from high to low or vice versa) that defines which operator takes an operand that is surrounded by two operators of different precedence (or priority). Multiplication normally has higher precedence than addition, [ 1 ] for example, so 3+4×5 = 3+(4×5) ≠ (3+4)×5.
