[b]Note:[/b] Unlike primitive [float]s which are 64-bit, numbers stored in [PoolRealArray] are 32-bit floats. This means values stored in [PoolRealArray] have lower precision compared to primitive [float]s. If you need to store 64-bit floats in an array, use a generic Array with [float] elements as these will still be 64-bit. However, using a generic Array to store [float]s will use roughly 6 times more memory compared to a [PoolRealArray].
Appends a [PoolRealArray] at the end of this array.

</method>
<methodname="empty">
<returntype="bool"/>
<description>
Returns [code]true[/code] if the array is empty.
</description>
</method>
<methodname="insert">
<returntype="int"/>
<argumentindex="0"name="idx"type="int"/>
<argumentindex="1"name="value"type="float"/>
<description>
Inserts a new element at a given position in the array. The position must be valid, or at the end of the array ([code]idx == size()[/code]).
</description>
</method>
<methodname="invert">
<description>
Reverses the order of the elements in the array.
</description>
</method>
<methodname="push_back">
<argumentindex="0"name="value"type="float"/>
<description>
Appends an element at the end of the array.
</description>
</method>
<methodname="remove">
<argumentindex="0"name="idx"type="int"/>
<description>
Removes an element from the array by index.
</description>
</method>
<methodname="resize">
<argumentindex="0"name="idx"type="int"/>
<description>
Sets the size of the array. If the array is grown, reserves elements at the end of the array. If the array is shrunk, truncates the array to the new size.
[b]Note:[/b] Added elements are not automatically initialized to 0 and will contain garbage, i.e. indeterminate values.
