 New
 - `«` and `»` are now valid as program delimiters. `<<` and `>>` are still valid
-- added `norm` as a synonym of `abs`
 - `test` command can also take a symbol as a parameter ; if the symbol contains a valid
 - entering the sign after the base (ex: 0x-1e2) is allowed

 - signed zero is the sign of zero is subject to change  compared to previous version, for example `-3 sqrt` now equals `(0.000000,1.732051)` instead of `(-0.000000,1.732051)`
