I sure that is.<br>

Did you test it? Can you do: src->getType()->isFloatTy()<div class="im"><br>
<br>
What could be other reasons for such error?<br>
<br></div>
The only other possibility I can think of is that src was created<br>
using a different context.<br>
<br>
Ciao, Duncan.<br>

It doesnt work it fails with assertation that cast is invalid .What<br>
could be done?<br>
<br>
<br>
Maybe src doesn't have Float type?<br>

Hi Yakov, that looks correct to me. You can also use CreateFPExt<br>
which is<br>
slightly simpler.<br>
<br>
Ciao, Duncan.<br>
<br>
<br>
I want to transfer value (Value* src) of the type `FloatTyID` to<br>
`DoubleTyID`(I<br>
need all floats to be saved as 8 bytes).I have tried:<br>
<br>
builder.CreateCast(llvm:: Instruction::FPExt, src,<br></div>
llvm::Type::getDoubleTy( llvmContext),””)<div class="im"><br>
<br>
I don`t know if I use CreateCast correctly and if this approach is<br>
correct at all.<br>
<br>
Thank you.<br>
<br>
Yakov<br>
