# numeric-units

The *numeric-units* **parser** will load data from a column in a source data table and map values to other values before producing a numeric **variable** within a **collection**.

It inherits attributes and behaviors from its parent: **parser** - *numeric*.

The *numeric-units* **parser** will parse a column value containing a number and a units string, and will extract the number part to become a **variable** within a **collection**.

## Attribute - units

```
{
  "parser_type": "numeric-units",
  "column": "cccc",
  
  // The units attribute is a string to remove to ensure
  // proper parsing as a number
  //
  "units": "$",
  
  "collection": "collection_name",
  "variable": "variable_name"
}
```
