> If I understand correctly, another difference between a FloatCollection and an OrderedCollection of Floats, besides the noted efficiency due to the use of FloatArray, is that a FloatCollection will store IEEE 32-bit single precision floats, while an OrderedCollection of Floats will store double precision floats. Is this correct? This is analogous to the current difference between an Array of Floats and a FloatArray.
