Trevas - VTL 2.1

Trevas 1.7.0 upgrade to version 2.1 of VTL.

This version introduces two new operators:

• random
• case

random produces a decimal number between 0 and 1.

case allows for clearer multi conditional branching, for example:

ds2 := ds1[ calc c := case when r < 0.2 then "Low" when r > 0.8 then "High" else "Medium" ]

Both operators are already available in Trevas!

The new grammar also provides time operators and includes corrections, without any breaking changes compared to the 2.0 version.

See the coverage section for more details.
