What's the floating point equivalent of 'first 'last ??

[dog.ee.lbl.gov!hellgate.utah.edu!fcom.cc.utah.edu!cc.utah.edu!eyring]

This may be a FAQ, but I wouldn't know where to look for the FAQ
if there was one.

What's the equivalent of 'first and 'last on a floating point type?

It's not 'small and 'large because 'small is the smallest POSITIVE
nonzero number in the type. (ie just above zero)

For example:

	type my_type is range -50.0 .. +75.0;

What I need are attributes which will return the -50.0 and the +75.0.

If it were all my own code I would put in constants, but we are 
interfacing with another code set here, ie I can't change their types.

eyring@cc.utah.edu asks
    What's the equivalent of 'first and 'last on a floating point type?

Answer: 'first and 'last.

Read the book!  Floating point types are explained in ARM 3.5.7 and
operations on them in 3.5.8.  See 3.5.8(3), and also the Note in
3.5.8(19).
