Evaluating a postfix expression is simpler than directly evaluating an infix expression
對后綴表達式求值比直接對中綴表達式求值簡單。You can use the following algorithm to evaluate postfix expressions
您可以用如下演算法對后綴表達式求值:Evaluating the postfix expression
對后綴表達式求值I hope you will find w3eval to be a useful online tool for evaluating expressions in a way that is more natural than the classical method
我希望您會發現w3eval是個對表達式求值有益的在線工具,它在某種程度上比經典的方法更簡單自然。In lazy evaluation, an expression is not evaluated as soon as it is bound to a variable, but when the evaluator is forced to produce the expression s value
在懶惰計算中,表達式不是在綁定到變量時立即計算,而是在求值程序需要產生表達式的值時進行計算。The classic approach to writing code to evaluate arithmetic expressions was described by donald knuth in 1962 see resources
編寫代碼對算術表達式求值的經典方法由donald knuth描述於1962年(請參閱Evaluate mathematical expressions quickly and accurately
快速精確的對數學表達式求值Value attribute s expression evaluates either to
屬性的表達式求值所得結果為Classic algorithms for expression evaluation
表達式求值的經典演算法The following algorithm is used to perform a single step of the evaluation of an expression
後面的演算法用於單步執行表達式求值:In versa, the context is a single value that is considered while evaluating an expression
在versa中,上下文是一個在對表達式求值時考慮的單一值。And returns a boolean value indicating whether or not the expression evaluates to an " empty " value
) ,並返回一個布爾值,該布爾值表示對表達式求值的結果是不是「空」值。Deterministic expressions always return the same result any time they are evaluated with a specific set of input values
在使用特定的輸入值集對確定性表達式求值時,它們始終返回相同的結果。The process of evaluation is similar to calculating by hand : while the expression contains parentheses, the subexpression inside the deepest nested pair of parentheses is evaluated
求值過程類似於手工計算:如果表達式中包含括號,先求嵌套最深的括號對中的子表達式的值。The w3eval applet can t make your trusty hp - 41 easier to use - as its name implies, it s an expression evaluator that runs only on the web
W3eval applet無法讓您可信賴的hp - 41更易用,正如它的名稱所暗示一個只能運行於web的表達式求值程序。When an update statement encounters an arithmetic error overflow, divide by zero, or a domain error during expression evaluation, the update is not performed
當update語句在表達式求值過程中遇到算術錯誤(溢出、被零除或域錯誤)時,則不進行更新。During expression evaluation when set arithabort is off, if an insert, delete or update statement encounters an arithmetic error, overflow, divide - by - zero, or a domain error, sql server inserts or updates a null value
如果set arithabort為off ,並且在對表達式求值的過程中insert 、 delete或update語句遇到算術錯誤(溢出、被零除或域錯誤) , sql server將插入或更新一個null值。Next, the lower and upper bound expressions are evaluated, insofar they are present ; defaults are zero and the sequence ' s length
下一步,在它們所出現的范圍內,對上下限表達式求值;預設值是零和序列長度。The position function returns a number equal to the context position and the last function returns a number equal to the context size from the expression evaluation context
Position函數返回上下文位置對應的數字, last函數返回表達式求值時的上下文大小對應的數字。Computer science s traditional methods for evaluating mathematical expressions are awkward and difficult for the untrained user ; software engineer nikola stepan aims to change all that
對于未經訓練的用戶來說,計算機科學領域中數學表達式求值的傳統方法即不順手又難以使用;軟體工程師nikola . stepan旨在改變這些傳統方法。分享友人
