Integer literals with an ``'L'`` or ``'l'`` suffix yield long integers (``'L'``
is preferred because ``1l`` looks too much like eleven!). Numeric literals
containing a decimal point or an exponent sign yield floating point numbers.
-Appending ``'j'`` or ``'J'`` to a numeric literal yields a complex number with a
-zero real part. A complex numeric literal is the sum of a real and an imaginary
-part.
+Appending ``'j'`` or ``'J'`` to a numeric literal yields an imaginary number
+(a complex number with a zero real part) which you can add to an integer or
+float to get a complex number with real and imaginary parts.
