RealMatrix doesnt like big numbers

In order to perform a LU Decomposition with Apache Commons Math, I implemented the following :

The original matrix as a double[][] :

A matrix :
1.9720119421779572E-13 -1.5495666760275814E-12 
8.940570999398516E-6 1.1377963306426943E-6

The operation of RealMatrix creation as Javadoc refers:

RealMatrix A_Rmatrix = MatrixUtils.createRealMatrix(A_matrix);

And the final results :

A_RMatrix : 
{0; -0}
{0.0000089406; 0.0000011378}

I understand that RealMatrix doesnt like "big numbers". I found that matrix dimensions are limited to (64, 64).

The problem is "big numbers" are not supported. How can I handle them?

Those numbers aren't very big, I'd even say *small* ;) Anyway, what's your question? – rustyx Jun 11 '18 at 20:58
How to support big (or small, iyo) numbers? – Gilles-Antoine Nys Jun 11 '18 at 21:01
Actually, there is an issue. But it is not linked with format. I still search for an answer but not in the scope of this post. Thank you @nustyx – Gilles-Antoine Nys Jun 18 '18 at 16:25
