[fpc-pascal] Choice of exceptions to use?

I'm working on code where the function take a (x, y) set of coordinates.
If the coordinates are out of range/bounds, I want to raise an exception
with a message explaining the reason and limits. I definitely don't want
to "silently do nothing".
Looking at these set of built-in exceptions:
I'm in two-minds as to which exception to raise. Seems my choices are:
* EArgumentException - an invalid argument was passed to the method
* ERangeException - I could interpret this as the values passed in,
were not in the allowed range.
Initially I was leaning towards the Range exception, but now I'm
thinking that maybe the Argument exception is more appropriate
(based on the descriptions seen in the linked docs).
What's your thoughts?
