使用 JavaScript 构建一个简单的单位转换器
首先,我们为每个类别定义转换函数。例如,要转换长度单位,我们有 kmToMilesEl 和 milesToKmEl 等函数。这些函数处理转换背后的实际计算。同样,我们具有燃油经济性和数字存储的转换功能。接下来,我们创建一个名为 conversions 的 JavaScript 对象来存储这些函数,并按它们各自的单位进行分vs2017 x64: error C2666 'operator /': 10 overloads have similar conversions, when using st

Item 24 explains why only non-member functions are eligible for implicit type conversions on all arguments, and it uses as an example the operator* function for a Rational class. This Item extends the discussion with a seemingly innocuous modification to
