Expressions

Examples of data s-expressions Nested lists can be written as S-expressions: ((milk juice) (honey marmalade)) is a two-element S-expression whose elements are also two-element S-expressions.

Words and expressions such as believes, estimates, plans, projects, anticipates, expects, intends, may, will, should or other similar words or expressions are typically used to identify forward-looking statements.

Also shared with Lisp are the implicit return of the last value in a block, and the fact that all statements have a value, and thus are also expressions and can be used in larger expressions themselves.

Alternative expressions There are many alternative expressions for y(φ), all derived by elementary manipulations.

Circuits are described by expressions containing variables, and two such expressions are equal for all values of the variables if and only if the corresponding circuits have the same input-output behavior.

Concepts and expressions of this sort are monadic or "one-place" concepts and expressions.

Depending on which expressions (also called terms) are allowed to occur in an equation set (also called unification problem), and which expressions are considered equal, several frameworks of unification are distinguished.

Expressions for the Hamiltonian Following are expressions for the Hamiltonian in a number of situations.

Expressions for the symbol-error rate of rectangular QAM are not hard to derive but yield rather unpleasant expressions.

For example: * An identity is an equality, contained in a theorem, between two mathematical expressions that holds regardless of what values are used for any variables or parameters appearing in the expressions.

Haskell has do-expressions and comprehensions, which together provide similar functionality to for-expressions in Scala.

In more complex expressions, the operators still precede their operands, but the operands may themselves be nontrivial expressions including operators of their own.

It is relatively uncommon, and is used chiefly to mark the predicate of a nominal sentence, in fixed adverbial expressions, and in expressions relating to measurements of length, weight, and the like.

Lambda terms The syntax of the lambda calculus defines some expressions as valid lambda calculus expressions and some as invalid, just as some strings of characters are valid programs and some are not.

Lisp programs are valid s-expressions, but not all s-expressions are valid Lisp programs.

Minced oaths main Minced oaths are euphemistic expressions made by altering or clipping profane words and expressions, to make them less objectionable.

Notation Expressions as operands Operands may be complex, and may consist of expressions also made up of operators with operands.

Overview In the following examples indentation and formatting are critical for parsing the code: expressions are terminated by the end of the line, lists of expressions need to be on the same level of indentation.

Proverbs may also become euphemistic means of making certain expressions in the Igbo society, thus the Igbo have come to typically rely on this as avenues of certain expressions.

Quine argued that the only ontologically committing expressions are variables bound by a first-order existential quantifier, and natural language expressions which were formalized using variables bound by first-order existential quantifiers.
