string operand的意思|示意

In particular, if one operand is a string and the other a number, the string will be converted to a number and the two operands then compared numerically. This can lead to subtle errors.

特别是，如果一个运算对象是字符串，另一个是数字，那么字符串将被转换为数字，然后再对两个数字进行数值比较。

The string format operation involves the processing of the FormatString, looking for format specification sequences, and using these sequences to format the associated data from the right operand.

字符串格式操作涉及处理FormatString、寻找格式定义序列和使用这些序列对右边的操作数中的相关数据应用格式。

If the character is an operand, append it to the result string.

如果字符是操作数，将它添加到结果字符串。
