Real numbers

[Tony Graham <tgraham@xxxxxxxxxxxxxxxx>]

Forgive my curiosity, but Section 8.5.7.1 of the standard says, in
part:

    The expression language provides two types of numbers:  reals and
    integers.  Integers are considered to be a subtype of reals, and
    reals are a subtype of numbers.  For example, the integer 3 is
    also considered to be a real number, which, in turn, is considered
    to be a (dimensionless) quantity.

Where is the definition of real numbers?  What should the result be of
(number? (sqrt -1)) if DSSSL does not support complex numbers?
