@nikic Very sorry for my late response.

Looking at the documentation for `bitcastToAPInt`
```
// This function creates an APInt that is just a bit map of the floating
// point constant as it would appear in memory.  It is not a conversion,
// and treating the result as a normal integer is unlikely to be useful.
APInt IEEEFloat::bitcastToAPInt() const {
```
The function does not convert the `float` into an `int`.
