<P> Other conventions are less common: Common Lisp and Macsyma / Maxima use Basic - like operators except for inequality, which is / = in Common Lisp and #in Macsyma / Maxima . Older Lisps used equal, greaterp, and lessp; and negated them using not for the remaining operators . </P> <P> Relational operators are also used in technical literature instead of words . Relational operators are usually written in infix notation, if supported by the programming language, which means that they appear between their operands (the two expressions being related). For example, an expression in Python will print the message if the x is less than y: </P> <P> Other programming languages, such as Lisp, use prefix notation, as follows: </P> <P> In mathematics, it is common practice to chain relational operators, such as in 3 <x <y <20 (meaning 3 <x and x <y and y <20). The syntax is clear since these relational operators in mathematics are transitive . </P>

The result of a relational operation is always
