<p>
Numeric constants are any numeric characters, preceded by an optional minus sign to indicate negative numbers, and an optional decimal followed by more numeric characters to indicate floating point values. Examples of decimal numbers includes:
</p>
<div class="table sectionedit2"><table class="inline">
<tr class="row0">
<th class="col0">Decimal Numbers</th>
</tr>
<tr class="row1">
<td class="col0">10</td>
</tr>
<tr class="row2">
<td class="col0">-234.567</td>
</tr>
<tr class="row3">
<td class="col0">56.87</td>
</tr>
<tr class="row4">
<td class="col0">0.0123</td>
</tr>
</table></div>
<p>
Very large and small numbers may also be represented in scientific E notation (added in version 0.9.9.46). <a href="http://en.wikipedia.org/wiki/Scientific_notation" class="urlextern" title="http://en.wikipedia.org/wiki/Scientific_notation" rel="nofollow">http://en.wikipedia.org/wiki/Scientific_notation</a>
</p>
<div class="table sectionedit3"><table class="inline">
<tr class="row0">
<th class="col0" colspan="2">Scientific E Notation</th>
</tr>
<tr class="row1">
<th class="col0">E Notation</th><th class="col1">Decimal Number</th>
</tr>
<tr class="row2">
<td class="col0">2e0</td><td class="col1">2</td>
</tr>
<tr class="row3">
<td class="col0">3e2</td><td class="col1">300</td>
</tr>
<tr class="row4">
<td class="col0">1.234e10</td><td class="col1">12340000000</td>
</tr>
<tr class="row5">
<td class="col0">-5.3e4</td><td class="col1">-53000</td>

<tr class="row6">
<td class="col0">2e-1</td><td class="col1">0.2</td>

<tr class="row7">
<td class="col0">5.12e-9</td><td class="col1">0.00000000512</td>
</tr>
</table></div>
<p>
Positive integer values may also be expressed in binary (base 2), octal (base 8), and hexadecimal (base 16). Precede binary values with 0b (0b1110 = 14), octal with 0o (0o177 = 127), and hexadecimal with 0x (0xff = 255).
