Why Accuracy Matters
Manual percentage calculations are prone to errors, especially when dealing with decimal points. The EzCalcy algorithm ensures precision up to 2 decimal places, making it reliable for financial reporting, medical dosages, and scientific data analysis.
✨ Pro-Tip: Percentages are reversible. 8% of 50 is exactly the same as 50% of 8. Knowing this can help you do quick mental math in a pinch!
