Percentage Calculator

Calculates 10 different percentage operations: how much X% of Y is, what percentage X is of Y, increase, decrease, percentage change, adding or subtracting a percentage, discount, margin, and markup, always showing the formula and the substitution with your own numbers. Clearly distinguishes margin from markup and percentage change from percentage points, and guards against division by zero.
