# numeric-constant

The *numeric-constant* **parser** does not load any data from a source data table. On the other hand, it will assign every **entity** identified by its associated **table** object into a numeric **variable** within a **collection**.

At first, it may seem useless to assign every **entity** the same numeric value within a **variable**. But it's not *every* **entity** - because this **parser** operates in conjunction with a **table** object, it's possible that the source data table contains rows that only match with a subset of **entities** loaded from the *entity_table*.

Thus, this **parser** is able to assign a constant number to all entities that were present in an *other_table*.

## Attribute - value

The *value* attribute is required.

```
{
  "parser_type": "numeric-constant", 
 
  // The value attribute becomes the value stored
  // in the variable
  //
  "value": ####,
  
  "collection": "collection_name",
  "variable": "variable_name"
}
```
