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].
