What are the rules for determining significant digits?

The rules for determining significant digits include

1. Counting all non-zero digits is significant

2. Any zeros between significant digits are significant

3. Zeros that are found to the right of both decimals and another significant digit are significant

4. Leading zeros that appear as placeholders are not considered significant.
