Where do you think the code and struct come from?!

If you have code for multiplication or division of two fixed points, should be immediately obvious whether it's power of two or not (I'd have to think a bit to even figure how you'd write a divider if it's not power of two)

```
float MathHelper::fp69ToFloat(uint16_t x) {
const float divider = float(1 << 9);
float int_part = (x >> 9);
float float_part = (x & (1<<10) - 1) / divider;
return int_part + float_part;
}
```
