how does this work if the double is 10.0, this do not convert to A which it would for a integer, it converts to 4024000000000000. Why?
Sometimes the double would be 10.0 for example, and sometimes it could be 12.3456.

Integers and floating point values are represented differently.  An integer 10 will be stored in memory as hex 0A, as you said.

However, IEEE defines different representations for floating point, as discussed at

So you'll never see 0x0A when looking at a floating-point 10.
