<return type="PackedFloat32Array" />
<description>
Returns a copy of the data converted to a [PackedFloat32Array], where each block of 4 bytes has been converted to a 32-bit float (C++ [code]float[/code]).
The size of the new array will be [code]byte_array.size() / 4[/code].
The size of the input array must be a multiple of 4 (size of 32-bit float). The size of the new array will be [code]byte_array.size() / 4[/code].
If the original data can't be converted to 32-bit floats, the resulting data is undefined.

<return type="PackedFloat64Array" />
<description>
Returns a copy of the data converted to a [PackedFloat64Array], where each block of 8 bytes has been converted to a 64-bit float (C++ [code]double[/code], Godot [float]).
The size of the new array will be [code]byte_array.size() / 8[/code].
The size of the input array must be a multiple of 8 (size of 64-bit double). The size of the new array will be [code]byte_array.size() / 8[/code].
If the original data can't be converted to 64-bit floats, the resulting data is undefined.

<return type="PackedInt32Array" />
<description>
Returns a copy of the data converted to a [PackedInt32Array], where each block of 4 bytes has been converted to a signed 32-bit integer (C++ [code]int32_t[/code]).
The size of the new array will be [code]byte_array.size() / 4[/code].
The size of the input array must be a multiple of 4 (size of 32-bit integer). The size of the new array will be [code]byte_array.size() / 4[/code].
