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 ).
Relational operators: < > = <= => <> Logical operators: * (AND) + (OR) Like Palo Alto Tiny BASIC on which it was based, Level I BASIC did not tokenize keywords like Microsoft BASIC but used abbreviations to reduce the amount of memory used by keywords, such as F. for FOR, G. for GOTO, P. for PRINT, and T. for THEN.
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.
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.
In computer programming, operators are constructs defined within programming languages which behave generally like functions, but which differ syntactically or semantically. Common simple examples include arithmetic (e.g. addition with + ), comparison (e.g. " greater than " with > ), and logical operations (e.g. AND , also written && in some ...

Other languages use different symbols for the two operators. [22] For example: In ALGOL and Pascal, the assignment operator is a colon and an equals sign (":=") while the equality operator is a single equals ("="). In C, the assignment operator is a single equals sign ("=") while the equality operator is a pair of equals signs ("==").
