that depends mainly on the compiler you use and the left-side-operats, which you omitted.<br />
if you have f = i *f for example, the i could be converted to a float,<br />
otherwise, having i = f * i, the f would become an int.<br />
also, most compilers will throw warnings telling you what they do at this position or how they expect you to explicitely typecast.

I'm using Visual C++... On linux I'm using GCC3...<br />
<br />
it's better to static_cast&lt;&gt;() it then? That way I'm always sure it's what I want on any compiler?

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
