数值函数

Recall the following odd function below, which determines whether a numeric argument is odd or even returning 1 for odd numbers and 0 for even numbers

回想下 odd 函数，它用于判断一个数值对象是奇数还是偶数奇数返回 1 ，偶数返回 0

Scanning each character in the expression to separate and record operators, operational symbols and data types of operators, when expression being correct in syntax, recording interpreter executive order based on precedence of operator, a general expression interpreter is designed. The interpreter not only is used for numerical value and string computation, but also is easy to extend its functions, and when batch converting data, it could catch run error and continue to successive data.

2通过对公式的一次扫描，记录操作数、操作符号和操作数的赋值特性，并在语法正确的情况下，记录公式基于算符优先级的解释执行顺序，设计了通用公式解释器，它不仅可以进行数值运算、字符运算，而且可以对使用的函数库方便地进行扩充，在批量进行数据转换时，可以记录运行时错误，而不影响后续数据的执行。

More than 30 kinds of meshfree methods are reviewed in this paper in the light of weighted residual method, and different meshfree methods can be viewed as different forms of weighted residual method and/or with different approximation functions. Various kinds of meshfree approximate schemes are presented in detail, including moving least square approximation, kernel and reproducing kernel approximation, partition of unity approximation, radial basis approximation, radial point interpolation and natural neighbor interpolation.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
