Are these rational numbers 0.1234, whole number -1,
and whole number 2345, respectively?

The first falls under either floating point types
or decimal fixed point types, the second is of some
integer type, as is the last one.  You should be
able to learn how you can define just the types
that you need, by using really any text on Ada, no matter
how old.

Frequently, there is no need to use any predefined types.
These may neither reflect your problem well, nor let you
see how to use types. If you follow any tutorial text that
you like, it will let you see what numeric types these are:

    type Part_No is range 1_000 .. 9_999;

    type Bits_16 is mod 2**16;

    type Temperature is delta 0.1 digits 4;

    type Flt is digits 6 range 0.0 .. 42_000_000.0;
