问题描述
你好,
我试图将双倍乘以花车(实际上我现在尝试了每一个
可能的组合)并且它永远不会起作用(好吧) ,它做了一些事情
但它总是错的)。我不知道它是什么以及在哪里寻找
帮助,也许有些人知道吗?
double = float * double; (或它的每种可能的组合)。一个例子:
0.3 * 0.7会导致1.7(有更多的数字)。有人知道吗?
如果我改变变量的类型我认为结果保持不变
(但我不是100%肯定)...

Hi there,
I am trying to multiply doubles with floats (actually I tried every
possible combination by now) and it never works (well, it does something
but it is always wrong). I have no idea what it is and where to look for
help, maybe some of you know?
double=float*double; (or every possible combination of it). An example:
0.3 * 0.7 would result in 1.7 (with lots more digits). Anyone any idea?
If I change the types of the variables I think the result stays the same
(but I am not 100% sure)...
