`float integers'? float is a floating point (real) number, int is an integer
(whole number). There is no such thing as a float integer. Array subscripts
have to be of an integer-compatible type, which float isn't, so change hf
to type int, if possible.

If you are still confused, send me a longer code sample and I'll show you
what to change.
