Percentage Increase v1.0.0

Calculate the percentage change between an old value and a new value. Determines whether the change is an increase or decrease, the absolute change, and the percentage change. Essential for financial analysis (stock price changes, revenue growth), scientific measurements (before/ after experiments), performance benchmarks, and population statistics. A positive percentage indicates growth; negative indicates decline. Division by zero (old_value = 0) is handled gracefully.
