Sparse float matrix

I’m totally new to TileDB, but I’m kind of shocked that dense float matrices aren’t supported: Creating Dimensions - TileDB Embedded Docs. It’s basically my default data type for a matrix.

I’m concerned that I’ll have to use a sparse matrix despite having no zeroes, which is probably going to take up more space and process slower than an equivalent dense. Are dense float matrices planned for the future? Or am I missing something about TileDB that makes this unnecessary?

Sorry, I just realised the mistake I made. Dimensions can’t be floats in a dense matrix, but attributes can. And attributes (as I just discovered) are the actual data contained within cells of the matrix.
