Bug #4577: (int...float).max should not raise an error

(int...float).max (without a block) will raise an error:

(({p (1...9.3).max # cannot exclude non Integer end value (TypeError)}))

I don't think it should do so.

int...float is a valid range object. When I construct such range, there's no error message.

The range can call all the Range instance methods. Only when calling single #max, the errmsg seems to tell that the range itself is not valid.

#max with a block will not raise the error:

(({p (1...9.3).max {|a,b| a <=> b} #=> 9}))

I think (1...9.3).max should also return 9( (end_obj-1).ceil ). If you admit the legality of #max(&block), you should also admit #max().
