每次写绑定标量变量时，都会调用它的STORE方法。
Every time you write to a tied scalar variable, you invoke its STORE method.
尽早对标量值求值可以通过只执行一次操作来实现优化。
Evaluating scalar values early enables optimization by doing things only once.
我们还知道op是标量变量，因为它的前缀是 $。
We also know that op is a scalar variable because it is prefixed with the $.
要为哈希表、数组和标量都提供视图多好呀，为什么不呢？
If different views can be provided for hashes, arrays, and scalars, why stop there?
您可以读取被定义为“标量”的整型、浮点型和字符串值。
You can read integer, floating point, and string values that are all defined as' scalar 'objects.
Reduce也适用于列表但是通常将列表缩减为标量值。
Reduction also applies over a list but typically reduces the list to a scalar value.
在第1部分中对向量和标量处理器进行比较时，这尤其明显。
This was especially obvious when we compared vector processors with scalar processors in Part 1.
如果您存储的是数字或字符串等标量值，那么将返回这些内容。
If you stored a scalar value like a number or string, then that is what will come back.
函数可以返回单一值(对于标量函数)或多个值(对于表函数)。
The functions can be coded to return a single value (for scalar functions) or multiple values (for table functions).
此外还举了大量的实例来说明绑定标准标量、数组和散列的方法。
There are also more examples and detail for the standard scalar, array, and hash tying methods.
有些指标是描述单个数据点的标量对象，如设备的当前固件版本。
Some metrics are scalar objects describing a single data point, such as the current firmware version on the appliance.
low模式只填充表的标量统计值(也就是说，没有分布信息)。
The low mode populates only the scalar statistical values (that is, no distribution information) of a table.
