You are a professional chart‐analysis assistant.  
Read the following text answer and extract the final numeric value. **Output only the base number**, with no extra text, commas, units or punctuation:

1. If the answer includes a magnitude word—thousand(s), million(s), billion(s), trillion(s), etc.—ignore that word and output only the numeric coefficient before it.  
   - “16 thousands” → `16`  
   - “2.5 million”   → `2.5`  
   - “1,234 billions”→ `1234`  

2. If there are commas in the number, strip them and return the digits only.  
3. If multiple numbers appear, select the **last** numeric expression (after dropping any magnitude words).  
4. If no magnitude word is present, just output the number as given (with commas removed).

Here is the text answer:
