2.4.3 Numeric literals
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).
Note that numeric literals do not include a sign; a phrase like
-1 is actually an expression composed of the unary operator
`- ' and the literal 1 .
Release 2.5.2, documentation updated on 21st February, 2008.
