  It's indefinite - array of this type can have various lengths, eg
short : my_array(1 .. 10);
long : my_array(1 .. 10000);
   If you said instead
type my_other_array is array(integer range 1 .. 50) of float;
  then you could say
x : my_other_array;
y: my_other_array;
  but you couldn't say
z : my_other_array(1 .. 10);
  since my_other_array type was defined with fixed bounds of 1 .. 50

  Boolean yes, Float no.  (How would you go about setting the initial
values of an array(float range 0.1 .. 0.2)?  x(0.100000001) := 1;
x(0.100000002) := 2; etc?)
