Describe behavior of floating-point number handling

[guimachiavelli]

As usual when dealing with floating-point numbers, users might see discrepancies between the data they send Meilisearch and the data they later see stored in their documents.

For example, @qdequele sent -0.75634628 to Meilisearch, but when checking the document this document saw -0.756346289634598 (so, the same number, but with increased precision). This is due to differences between the actual value of the number and the way computers represent these numbers to us in a human-readable way.
