No. But in both cases you can do an explicit Unchecked_Conversion to
convert a pointer to one thing into a pointer to something else. You are
then explicitly telling the compiler, and future maintainers of your
program, something like "yes, I know I'm calling a function that expects
two Floats with just a single Character, but I've thought about it and
it's correct in this case."
