Octave's built-in numeric objects include real, complex, and integer
 
37
scalars and matrices.  All built-in floating point numeric data is
 
38
currently stored as double precision numbers.  On systems that use the
 
39
IEEE floating point format, values in the range of approximately
 
40
 2.2251e-308 to 1.7977e+308
 
41
 can be stored, and the relative precision is approximately
 
42
 2.2204e-16. 
 
43
The exact values are given by the variables <code>realmin</code>,
 
44
<code>realmax</code>, and <code>eps</code>, respectively.
 
45
 
 
46
   <p>Matrix objects can be of any size, and can be dynamically reshaped and
 
47
resized.  It is easy to extract individual rows, columns, or submatrices
 
48
using a variety of powerful indexing features.  See <a href="Index-Expressions.html#Index-Expressions">Index Expressions</a>.
