Is this normal or a bug ?

Hello, d community! I am currently exploring the possibilities of 
interoperability between C++ and D. While conducting some tests, 
I came across an interesting case. Here is the C++ code snippet:

```cpp
float float_test(float x, float y){
   return x+y;
}
```

And here is the corresponding D code:

```d
extern (C++) float float_test(float x, float y);
{
   assert(10.1 + 20.6 == float_test(10.1, 20.6));
}
```

Unfortunately, the assert statement fails in this case. I'm 
wondering if this discrepancy is due to the different float 
representations, a bug, or if I'm doing something wrong. Any 
insights would be greatly appreciated!
