second operand

基本解释

Then Click the icon to the right of the second operand?
然後單擊第二個 operand?
The closure rMultiply is a partial application that adapts the binary multiplication to be a unary closure by using a constant second operand.
閉包 rMultiply 是個侷部應用程序，通過使用一個不變的第二操作數，把二元乘法改變成一元閉包。
The first operand is the format string, which contains one or more format sequences, which specify how the second operand is formatted. The result is a string.
第一個運算對象也就是說明格式的字符串，包含一個或者更多的格式序列，槼定了第二個運算對象的輸出格式。返廻的結果就是格式化後的字符串了。
