<p>src/pmc/float.pmc - Floating-point number</p>
<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p><code>Float</code> extends <code>scalar</code> to provide floating-point number operations.</p>
<h2><a name="Functions"
>Functions</a></h2>
<dl>
<dt><a name="void_init()"
><b><code>void init()</b></code></a></dt>
Initializes the number to zero.
<dt><a name="PMC_*clone()"
><b><code>PMC *clone()</b></code></a></dt>
Make an exact copy of this PMC.
<dt><a name="FLOATVAL_get_number()"
><b><code>FLOATVAL get_number()</b></code></a></dt>
Returns the value of the number.
<dt><a name="INTVAL_get_integer()"
><b><code>INTVAL get_integer()</b></code></a></dt>
Returns an integer representation of the number by truncating (rounding toward zero).
<dt><a name="INTVAL_get_bool()"
><b><code>INTVAL get_bool()</b></code></a></dt>
Evaluates the number as a boolean,
i.e.
it's true if it's not zero.
<dt><a name="STRING_*get_string()"
><b><code>STRING *get_string()</b></code></a></dt>
Returns a Parrot string representation of the number.
<dt><a name="STRING_*get_repr()"
><b><code>STRING *get_repr()</b></code></a></dt>
<dt><a name="void_set_integer_native(INTVAL_value)"
><b><code>void set_integer_native(INTVAL value)</b></code></a></dt>

<dt><a name="void_set_number_native(FLOATVAL_value)"
><b><code>void set_number_native(FLOATVAL value)</b></code></a></dt>
Sets the value of the number to <code>value</code>.
<dt><a name="void_set_string_native(STRING_*value)"
><b><code>void set_string_native(STRING *value)</b></code></a></dt>
Sets the value of the number to the value of <code>*value</code>.Note that this method morphs the number into a <code>String</code>.

><b><code>INTVAL cmp(PMC *value)</b></code></a></dt>
The <code>cmp</code> operation.
<dt><a name="INTVAL_cmp_num(PMC_*value)"
><b><code>INTVAL cmp_num(PMC *value)</b></code></a></dt>
Returns the result of comparing the number with <code>*value</code>.
<dt><a name="void_increment()"

Used to archive the number.
<dt><a name="void_thaw(PMC_*info)"
><b><code>void thaw(PMC *info)</b></code></a></dt>
Used to unarchive the number.</dl>
