Feature tours · Number fields

Build calculations into the work itself

Advanced number fields with extensive customization and math library.

For example: an order form that totals and discounts each order as the customer types, and keeps quantities in range. The same fields, settings and functions build anything you can imagine for your business.

Prices, money and rates that read right

Three field types hold numbers. Each takes the same settings, and each input is only as wide as the values it holds, so a form reads cleanly.

• Decimals: how many digits a value keeps and shows.
• Min value and Max value: a value outside the range is pulled back to it, whether someone types it or a calculation writes it. A minimum of 0 keeps prices and counts from going negative.
• Width: from 4em for a two-digit quantity to 12em for large amounts. New fields get a width that fits their type.

Answers appear while someone types

Calculations are equations on the fields themselves. Subtotal is {quantity} × {unitPrice}, the discount comes off, and so on. Each input runs them whenever it changes, so there’s no Calculate button to press.

• Write equations with +, −, ×, ÷ and any field in {braces}.
• Chain results: one equation can use another’s result.
• Add a change rule to each input, and every result follows any edit.

Results that are easy to read

A Result field shows a calculated value the way it should read. Choose a Format and Decimals in its settings.

• Currency: $539.89. Number: 599,880. Percentage: 10%.
• Short date, Long date and Time, in each visitor’s own format.
• Decimals rounds: 539.89 with 0 decimals shows 540.

Change one value, and every result follows

Change Quantity from 12 to 2 and every result recalculates: subtotal $99.98, total $89.98, and shipping is no longer free.

Bad numbers never get in

Type 500 into Quantity and it becomes 100, its maximum, the moment you leave the field. Everything calculated from it updates too.
