square - multiply a number by itself

(import (scheme base))              ;R7RS

(square z)

Returns the square of z. This is equivalent to (* z z).

Returns a single value which is a number.

(square 42)  => 1764
(square 2.0) => 4.0

Only exists in R7RS. Can be replaced with (lambda (z) (* z z)).

It is an error for this procedure to be passed the wrong number of arguments, and it is an error if z is not a complex number object. Implementations may signal an error, extend the procedure's domain of definition to include such arguments, or fail catastrophically.
