How to use it

{'step': 1, 'description': 'Find absolute difference: 1,487.50 - 1,250 = 237.50'}
{'step': 2, 'description': 'Divide by initial value: 237.50 ÷ 1,250 = 0.19'}
{'step': 3, 'description': 'Convert to percentage: 0.19 × 100 = 19%'}
{'step': 4, 'description': 'Result: 19% increase from 1,250 to 1,487.50'}

Common mistakes

⚠️ Dividing by final value instead of initial value
⚠️ Not using absolute value of initial when it's negative
⚠️ Confusing percentage point change with percentage change

Worked example

Calculate change from 50 to 75.

The cambio_pct of {cambio_pct}% represents the relative change from initial to final value, while differentiate ({diferencia}) shows the absolute numeric difference.
