1 | What has been changed in Singular 4 {#changes_in_sw_page} |
---|
2 | =================================== |
---|
3 | |
---|
4 | 1. lots of stuff moved in the headers, which messes up the includes. This should be fixed already. |
---|
5 | If there is still a problem look in `test.cc` for the correct includes. |
---|
6 | 2. coefficients were separated from polynomial rings. |
---|
7 | * There is a new type `coeffs`. |
---|
8 | * Operations on `coeffs` are done by `n_*` functions, where `coeffs` is the last argument (consider it as the context storing information on the coefficient domain). |
---|
9 | * Functions like `nAdd(a, b)` become `n_Add(a, b, r)`. |
---|
10 | 3. new arithmetic functions. |
---|
11 | * Same as the previous. |
---|
12 | * Arithmetic is done with `p_*` functions, which take a ring as the last argument. |
---|
13 | * The use of the global variable `currRing` is discouraged. |
---|
14 | 4. please use ring methods (e.g. rVar(r)) instead of (currRing specific) global variables (e.g. `pVariables`) |
