What is the data type for the number 9.6352
in Java?
Actually if I postfix the number with d or f . then it will be quite easy to decide. But if I leave it as alone, then which will be the default type of the number in java?

检查JLS关于浮动点字面的一节(第3.10.2段):
浮动点的字面是指以ASCII字母F或f加以补充的浮动体;否则,其类型是双重的,因此可以选择性地用ASCII字母D或D加以补充。
So it s a double if it s not suffixed.
By default, any floating point data type without f or F postfixed, is considered as of type double
.
Since the given number doesn t end with f / F , it is of type double
.
我们可在最后添加d或D,将其作为<条码>杜布尔条码>的类型,但也是任择的。
