### 2.8.10 Access to PARI/GP commands: `pari`

- `pari` with a string as first argument (the PARI command name) execute the corresponding PARI command with the remaining arguments. For example `pari("weber",1+i)` executes the PARI command `weber` with the argument `1+i`.
- `pari` without argument exports all PARI/GP functions
  - with the same command name if they are not already defined inside `Xcas`
  - with their original command name with the prefix `pari_`
  For example, after calling `pari()`, `pari_weber(1+i)` or `weber(1+i)` will execute the PARI command `weber` with the argument `1+i`.

The documentation of PARI/GP is available with the menu Help->Manuals.
