@section{description}
An array of 64-bit double precision floating point numbers.
Note that despite not having "Float" in its name, DoubleArray does in fact hold
a sequence of SuperCollider double precision link::Classes/Float##floats::.
For a raw array of 32-bit floats, use link::Classes/FloatArray::.
FloatArray and its subclass link::Classes/Signal:: are commonly used to hold
audio data in SuperCollider. Since almost all audio has 16-bit or 24-bit
precision, using double precision floats for this purpose would be a waste of
space. In other words, use FloatArray for audio, and DoubleArray for precise
math operations.
The complete list of RawArray types in SuperCollider is:
@section{list}
## link::Classes/Int8Array:: - 8 bit integer
## link::Classes/Int16Array:: - 16 bit integer
## link::Classes/Int32Array:: - 32 bit integer
## FloatArray - 32 bit floating point
## DoubleArray - 64 bit floating point
## link::Classes/SymbolArray:: - symbols
