sqlite type-name with two optional signed numbers, what does it mean?

I guess this is a very naive question but could not goolge it.

I see in various pages on sqlite site that mention a type-name can have up to 2 signed numbers

In the later there is an example DECIMAL(10,5)

What this mean? I suppose it is a kind of magnitude/precision, what would 2 numbers mean for both integer and text?

Thanx in advance. Phi
