Return a0 as a result of the expression . Return a0 as a result of the expression .
I must ask the prince about this, for the expression is his. 没有正则表达式 引擎可以保证在线性时间内执行这种匹配。 No regexp engine can guarantee evaluating these in linear time. Return the new value of a as a result of the expression . Theano:快速计算数学表达式 的Python框架”。 Theano: A Python framework for fast computation of mathematical expressions .". Is表达式 现在在右边可以有一个模式,而不只是一个类型. Is expressions can now have a pattern on the right hand side, instead of just a type. If A and B are both SS expressions , then AB is also an SS expression . 先判断表达式 1的值是否为真,如果是真的话执行表达式2;. It is first judged whether the value of the expression 1 is true, if it is true, the expression 2 is executed; FormatdateTime()函数返回表达式 ,此表达式已被格式化为日期或时间. FormatDateTime Returns an expression formatted as a date or time. 值计算(valuecomputation):计算表达式 所返回的值。 Value computations: calculation of the value that is returned by the expression . 编译之后,JSX表达式 就变成了常规的JavaScript对象。 After compilation, the expressions made using JSX become regular JavaScript function calls. 因此,表达式 a1与模式a1匹配,而与模式'a1'(a1后加一个空格)或a1_不匹配。 Therefore, the expression a1 matches the pattern a1, but not the patterns'a1'(a1, with a space after it) or a1_. 我们再一次注意到,函数表达式 _e仍然在内存中,唯一原因是它被储存到了已声明的变量e上。 Once again I notice that function expression _e is still in memory only because it is saved to declared variable e. Rateprincipal”表达式 的值被赋给了interest变量。 The value of the expression rate* principal is being assigned to the variable interest.然而,匿名函数(通过函数表达式 或者函数构造器创建)没有名称。 However, an anonymous function(which can be created by a function expression or the Function constructor) does not have a name. 在这个例子里,表达式 1+1==2的求值结果为True,所以assert语句没有做任何事情。 In this case, the expression 1+ 1== 2 evaluates to True, so the assert statement does nothing. Rate表达式 在创建计划事件规则时启动,然后按照其定义的计划运行。 The rate schedule expression will start when you create the Scheduled Event rule and then run at the rate defined thereafter. 如果你必须使用CSS表达式 ,那么一定要记住,它们可能要运行成千上万次,有可能会影响以哦面性能。 If you must use CSS expressions , remember that they may be evaluated thousands of times and could affect the performance of your page. 例如,表达式 2**0.5计算2的平方根,但是该值的平方不会完全恢复成2。 For example, the expression 2** 0.5 computes the square root of 2, but squaring this value does not exactly recover 2. 早期版本的JavaScript不允许使用命名函数表达式 ,出于这样的原因,你不能创建一个递归函数表达式。 Early versions of JavaScript did not allow named function expressions , and for this reason you could not make a recursive function expression. CSS表达式 是强大的(可能也是危险的)设置动态CSS属性的方法。 CSS expressions (supported in IE beginning with Version 5) are a powerful, and dangerous, way to dynamically set CSS properties. Price*quantity-此表达式 引用文档中名为“price”和“quantity”的其他两个字段。 Price* quantity- This expression references two other fields within the document called“price” and“quantity”. 表达式 必须全部转换为通用的数据类型,这将成为结果的类型(详见10.5节)。The expressions must all be convertible to a common data type, which will be the type of the result(see Section 10.5 for details). 函数表达式 可以有一个名字,比如sum=functionname(a,b),但是name只在该函数内可见。 Function expressions can have a name, like sum= function name(a, b), but that name is only visible inside that function. 例如,表达式 1+futurefactorial(n)可以创建一个新的future,其行为类似于数字1+factorial(n)。 For example, the expression 1+ future factorial(n) can create a new future that will behave like the number 1+factorial(n). Match表达式 必须是穷尽(exhaustive)的,意为match表达式 所有可能的值都必须被考虑到。 Match expressions are required to be exhaustive, in the sense that all possibilities for the value in the match expression must be accounted for.
