Does anybody know, what I must to do to work with negative values of product_id?
How can I fix it? or are any more problems with negative values of id?
(I am using 3.x Ultimate version)

What is the purpose of this, if i may ask?
The DB defines the product_id field(s) as unsigned. Why would you want a signed product_id?
Our main application which manage the products have own base (and there values of some id's are negative), and I must connect the main application with the shop. I imported the data to cscart shop (in db I unset unsigned attr in the product_id field). I can't change the values to possitive.
After import nn the product page I have got the error in function name:
There are sing '-', and I don't know how (and where in the code) to fix it…
I have a problem when I put products to the cart. Cscart request that the functions fn_ceil_to_step and fn_floor_to_step doesn't exist. I checked the files and didn't find this kind of functions.
Bad Idea to have negative product_ids and change cs-cart default functionality. Use some workaround to translate those negative values to positive
Does it really use negative numbers for product_ids in your other system? That seems very odd. It could be that the product_ids are simply bigger than the 8 character value used in the table definition. If so, just make the field bigger (like 12).
But it is a bad idea to change these to being signed values. Your store shouldn't deal with product_ids from a foreign source. You should either use that as the product_code or create a Product Feature to store the foreign system's reference.
