In Vimscript, as in c, only the numeric value zero is false in a Boolean context; any non-zero numeric value-whether positive or negative-is considered true.

和c一样，在Vimscript中，对于布尔值来说，只有数值0为假；任何非0数值—不管是正数还是负数—都为真。

Enumerations and numeric ranges: For example, the value of a particular string attribute must be a, c, or D. Another example: the value of a particular numeric must be between 1 and 500.

枚举与数字范围：例如，某个特定字符串属性必须为A、c或者d。再比如，某个特定的数字必须在1至500之间。

Now we're not dealing with C and C arrays but also want to use string offsets so we need a function to calculate a numeric value, a hash, for each key.

现在我们处理的不是C语言和它的数组，我们想用字符串偏移量，所以我们需要一个哈希函数，为每个键值计算出一个数值。
