2.4.3 Numeric literals
</H2>

<P>
There are four types of numeric literals: plain integers, long
integers, floating point numbers, and imaginary numbers.  There are no
complex literals (complex numbers can be formed by adding a real
number and an imaginary number).

<P>
Note that numeric literals do not include a sign; a phrase like
<code>-1</code> is actually an expression composed of the unary operator
`<code>-</code>' and the literal <code>1</code>.
