Arithmetic

Card → Enable Formula

Parentheses (Nested Cards)

Deeper Cards compute before their parent(s). Therefore, Nested Cards act like parentheses. They have an operator unless they are the first formula item.

Rounding

Presets

Card → Formula Presets

To remove a preset, re-click the active preset button.

Selectors

Formulas use the selected Entry Value.

Checkboxes

Internally, a Checkbox value is 1 or 0. This example multiplies that value by $5.00 (a "Hidden in Previewer" Entry) using a formula. Effectively, this is a no-code conditional form.

Alternatives to Formulas

The next document is about integrating JavaScript. Therefore, you can also write formulas like:

function ({ radius }) {
  return Math.PI * radius.value ** 2
}
