[Mono-ue] float test

With preview 4 (and 3) I have been unable to have a method like this:

[UFunction, BlueprintCallable]
public float FloatTest(float invalue)
{
   Console.WriteLine ("invalue = {0}", invalue);
   return invalue * 2.5f;
}

And then try to call that method from a BP (screenshot

2.5, but the output is:
LogMono: invalue = 6.586103E-44

And I receive a stack like this:
