I've been given an RNA count matrix and metadata files and asked to do differential expression analysis and when I inspected the data found that the count matrix contained decimal values and DESeq2 can't process it, so how to solve this knowing that I don't have any further information about the data how it's processed.,

the data is not normalized nor log transformed

sorry, I'm novice in DE analysis, but wouldn't this change the data? Or the fractions doesn't really matter?

Yes, it will convert all the decimal values to integer, by shifting either up or down. This doesn't really matter though, as you are only shifting each value by less than 1.
