Fun with numbers - dammit, but I want a cast!

Some casts do. Some merely invoke conversions.

But the C++ equivalent, something like (float) 1, would _not_ return the
floating point number with the same bit pattern as 1L either. It would
simply invoke the conversion from int to float. What you're talking
about would be something like *(float *) &i.
