Double absolute value

[truebluepl]

Description

I would like to compute double absolute value. E.g: ||3-5|-4|

Actual Behavior

Typed expression is parsed as Latex value: |{|{3-5}|}-4|, which causing error when I try to evaluate.

Expected Behavior

Result should be 2.

It works ok. My fault was setting latex expression for key as: |{#0}|, but should be: |#0|

Ok, I still have problem.

let ce = new ComputeEngine.ComputeEngine();
console.log(ce.parse('||3-5|-4|').evaluate().latex);

Result of above is: \error{|}

Should returns 2.
