DL4j - Rounded floating points when converting from Java Array to INDArray

Question

Converting from Java array to INDArray causes values to be rounded to nearest approximation

Actual behaviour

From Java Array - [0.0025249954778701, -0.0046458570286632, 0.0052295182831585, -0.0014667856739834, -0.0044226963073015, 0.0073519190773368, -0.0003814829979092, -0.0084274942055345, -0.0040481365285814, 0.0082860253751278]

To INDArray- [0.00, -0.00, 0.01, -0.00, -0.00, 0.01, -0.00, -0.01, -0.00, 0.01]

Expected behaviour

From Java Array - [0.0025249954778701, -0.0046458570286632, 0.0052295182831585, -0.0014667856739834, -0.0044226963073015, 0.0073519190773368, -0.0003814829979092, -0.0084274942055345, -0.0040481365285814, 0.0082860253751278]

To INDArray- [0.0025249954778701, -0.0046458570286632, 0.0052295182831585, -0.0014667856739834, -0.0044226963073015, 0.0073519190773368, -0.0003814829979092, -0.0084274942055345, -0.0040481365285814, 0.0082860253751278]

Below is the code

var (left, right) = inoc.splitAt(7840)
var bias :INDArray = Nd4j.create(right);
var weights :INDArray = Nd4j.create(left);

Answer 1

The default data type is float in the latest version. This is due to memory reasons.

Please ensure you create your arrays with double precision if that's what you're desiring.
