* expression evaluation is defined to be performed in one of three well-defined methods, indicating whether floating point variables are first promoted to a more precise format in expressions: FLT_EVAL_METHOD == 2 indicates that all internal intermediate computations are performed by default at high precision ( long double ) where available ( e. g. 80 bit double extended ); FLT_EVAL_METHOD == 1 performs all internal intermediate expressions in double precision ( unless an operand is long double ); FLT_EVAL_METHOD == 0 specifies each operation is evaluated only at the precision of the widest operand of each operator.

expression and evaluation
is an example of associativity because the parentheses were changed ( and consequently the order of operations during evaluation ) while the operands 5, 2, and 1 appeared in exactly the same order from left to right in the expression.
* If there is no data dependency between two pure expressions, then their order can be reversed, or they can be performed in parallel and they cannot interfere with one another ( in other terms, the evaluation of any pure expression is thread-safe ).
Within the parlance of Icon, the evaluation of an expression or function results in a result sequence.
Micro-Planner had a construct, called " thnot ", which when applied to an expression returns the value true if ( and only if ) the evaluation of the expression fails.
In programming language theory, lazy evaluation or call-by-need is an evaluation strategy which delays the evaluation of an expression until its value is needed ( non-strict evaluation ) and which also avoids repeated evaluations ( sharing ).
When using delayed evaluation, an expression is not evaluated as soon as it gets bound to a variable, but when the evaluator is forced to produce the expression's value.
That is, a statement such as ( i. e. the assignment of the result of an expression to a variable ) clearly calls for the expression to be evaluated and the result placed in, but what actually is in is irrelevant until there is a need for its value via a reference to in some later expression whose evaluation could itself be deferred, though eventually the rapidly growing tree of dependencies would be pruned to produce some symbol rather than another for the outside world to see.
In many other languages, evaluation can be delayed by explicitly suspending the computation using special syntax ( as with Scheme's "" and "" and OCaml's "" and "") or, more generally, by wrapping the expression in a thunk.
The heading and body of the table resulting from evaluation of some query are determined by the definitions of the operators used in the expression of that query.
However, because a referentially transparent expression can be evaluated at any time, it is not necessary to define sequence points nor any guarantee of the order of evaluation at all.
Increasingly, however, XSLT processors use optimization techniques found in functional programming languages and database query languages, such as static rewriting of an expression tree ( e. g., to move calculations out of loops ), and lazy pipelined evaluation to reduce the memory footprint of intermediate results ( and allow " early exit " when the processor can evaluate an expression such as without a complete evaluation of all subexpressions ).
* Delay ( programming ), a programming language construct for delaying evaluation of an expression
A deictic center, sometimes referred to as an origo, is a set of theoretical points that a deictic expression is ‘ anchored ’ to, such that the evaluation of the meaning of the expression leads one to the relevant point.
In eager evaluation an expression is evaluated as soon as it gets bound to a variable.
The term is typically used to contrast lazy evaluation, where expressions are only evaluated when evaluating a dependent expression.

He mentions the beats only once '', when he refers to their having revived through mere power and abandonment and the unwillingness to, commit death in life some idea of a decent equivalent between verbal expression and actual experience,, but the entire narrative, is written in the tiresome vocabulary `` of '' that lost `` and '' dying cause, `` and in the '' `` sprung syntax that is supposed to supplant, our mother, tongue.
The general theory of resonance shifts is used to derive a general expression for the second moment Af of a polycrystalline paramagnetic sample and is specialized to Af.
for, using the fact that N and N' commute Af and so when R is sufficiently large every term in this expression for Af will be 0.
It then follows that Af is large enough, but this is not obvious from the above expression.

The above expression is only ten words long, so this integer is defined by an expression that is under eleven words long ; it is definable in under eleven words, and is not the smallest positive integer not definable in under eleven words, and is not defined by this expression.
This is a paradox: there must be an integer defined by this expression, but since the expression is self-contradictory ( any integer it defines is definable in under eleven words ), there cannot be any integer defined by it.
