Decimal (Floating Point) Component

Decimal

Function: a!floatingPointField()

Displays and allows entry of a single decimal number, stored with a floating point representation.

When working with an integer, use an integer component. To display a number using a custom format, use a text component.

Notes

  • If you want to display a number with thousand separators or with special formatting such as a currency, use the text component.
  • Whether placeholder text clears on focus or input varies by device and browser. Placeholder text does not display on Microsoft Internet Explorer 9.
