Add Line Numbers
Add sequential line numbers to text.
How this calculation works
Each line is prefixed with its number, right-aligned and padded so they line up regardless of how many lines there are.
What the results mean
- Padding
- Numbers are padded to equal width, so 1 and 100 align neatly down the left edge.
