A PRACTICAL GUIDE

How to use the Number Format Generator.

Number formats change display, not the underlying value. Confirm how zero, negative values and decimals should appear.

Make the workflow fit your task.

Describe how positive, negative, zero and text values should display, including precision and units. Distinguish formatting from rounding stored values. Test representative numbers in the target application's locale, checking whether the display conceals meaningful precision.

Decisions and troubleshooting.

Does showing two decimal places round the stored number?

A display format normally changes presentation only. Use an explicit rounding calculation when the underlying result must change.

Why does a percentage format show 2500% instead of 25%?

The stored value may be 25 rather than 0.25. Confirm the data convention before changing the format or scaling values.

Try it with your own source.
