Why might a result be rounded?

The short answer

Results are shown to a sensible number of decimal places for the calculator, two for money for example, so long numbers stay easy to read. The calculation itself uses the full values you enter.

Why your hand total may differ

Because the page rounds only what it displays, adding the rounded parts yourself can give a slightly different total. The difference is usually a paisa.

How to check a result

1. 1Scroll below the calculator to the formula and the worked example.
2. 2Work the example with your own numbers, keeping every digit until the last step.
3. 3Round only at the end and compare with the total shown.

Good to know

• Rounding affects what is displayed, not the figure the calculator uses internally.
• Calculators are for guidance, so treat a rounded figure as a close reading, not a promise of exactness.
• If the answer is wildly different from your expectation, the cause is more likely an input than rounding.

Rounding is a display choice, so it does not change how your inputs are used. You can enter as many digits as you like and the calculation keeps them.

Two calculators can also show a different number of decimals, because what counts as sensible depends on what is being measured. Money uses two decimals, while other results may show more or fewer.
