 The precise type of a *number* may vary across BQN implementations or instances. A *real number* is a member of some supported subset of the [extended real numbers](https://en.wikipedia.org/wiki/Extended_real_number_line), that is, the real numbers and positive or negative infinity. Some system must be defined for rounding an arbitrary real number to a member of this subset, and the basic arithmetic operations add, subtract, multiply, divide, and natural exponent (base *e*) are defined by performing these operations on exact real values and rounding the result. The Power function (dyadic `⋆`) is also used but need not be exactly rounded. A *complex number* is a value with two real number *components*, a *real part* and an *imaginary part*. A BQN implementation can either support real numbers only, or complex numbers.
 
-An *array* is a rectangular collection of data. It is defined by a *shape*, which is a list of non-negative integer lengths, and a *ravel*, which is a list of *elements* whose length (the array's *bound*) is the product of all lengths in the shape. Arrays are defined inductively: any value (of a value or function type) can be used as an element of an array, but it is not possible for an array to contain itself as an element, or an array that contains itself, and so on.

Types other than array are called *atomic types*, and their members are called *atoms*.
