Converting WOQL-JS to WOQL-JSON to WOQL-JS did not work: `SYNTAX ERROR: WOQL.decimal is not a function`

[alexander-mart]

After toogle mode to JSON and back to WOQL and again to JSON (two times) with example query from docs i receive error: WOQL.decimal is not a function

Doc page: https://terminusdb.com/docs/maths-based-queries-in-woql/

How to reproduce:

1. Paste example in WOQL-mode and run: SERVER ERROR: Not well formed WOQL JSON-LD

   let v = Vars("result");
   evaluate(times(2,3), v.result)

2. Convert to JSON:

   {
   "@type": "Eval",
   "expression": {
   "@type": "Times",
   "left": {
     "@type": "ArithmeticValue",
     "data": {
       "@type": "xsd:decimal",
       "@value": 2
     }
   },
   "right": {
     "@type": "ArithmeticValue",
     "data": {
       "@type": "xsd:decimal",
       "@value": 3
     }
   }
   },
   "result": {
   "@type": "ArithmeticValue",
   "variable": "result"
   }
   }

3. Convert to WOQL:

   WOQL.eval(WOQL.times({"@type":"xsd:decimal","@value":2}, {"@type":"xsd:decimal","@value":3}), "v:result")

4. Convert to JSON:

   {
   "@type": "Eval",
   "expression": {
   "@type": "Times",
   "left": {
     "@type": "xsd:decimal",
     "@value": 2
   },
   "right": {
     "@type": "xsd:decimal",
     "@value": 3
   }
   },
   "result": {
   "@type": "ArithmeticValue",
   "variable": "result"
   }
   }

5. Convert to WOQL:

   WOQL.eval(WOQL.times(WOQL.decimal(2), WOQL.decimal(3)), "v:result")

6. Convert to JSON: :x: SYNTAX ERROR: WOQL.decimal is not a function

From Discord:

LaurentS: We tried replacing xsd:decimal with its equivalent (according to the docs) xsd:double but it didn't help.

@GavinMendelGleason Give me a hint where to look at the code that is responsible for this? I'll try to find a bug or missing method
