number Field Type

Renders an input text field and specializes in handling number input. This type offers different options for the precision, rounding, and grouping that you want to use for your number.

Field Options


type: integer default: Locale-specific (usually around 3)

This specifies how many decimals will be allowed until the field rounds the submitted value (via rounding_mode). For example, if precision is set to 2, a submitted value of 20.123 will be rounded to, for example, 20.12 (depending on your rounding_mode).


type: integer default: IntegerToLocalizedStringTransformer::ROUND_DOWN

If a submitted number needs to be rounded (based on the precision option), you have several configurable options for that rounding. Each option is a constant on the Symfony\Component\Form\Extension\Core\DataTransformer\IntegerToLocalizedStringTransformer:

  • IntegerToLocalizedStringTransformer::ROUND_DOWN Rounding mode to round towards zero.
  • IntegerToLocalizedStringTransformer::ROUND_FLOOR Rounding mode to round towards negative infinity.
  • IntegerToLocalizedStringTransformer::ROUND_UP Rounding mode to round away from zero.
  • IntegerToLocalizedStringTransformer::ROUND_CEILING Rounding mode to round towards positive infinity.
  • IntegerToLocalizedStringTransformer::ROUND_HALFDOWN Rounding mode to round towards “nearest neighbor” unless both neighbors are equidistant, in which case round down.
  • IntegerToLocalizedStringTransformer::ROUND_HALFEVEN Rounding mode to round towards the “nearest neighbor” unless both neighbors are equidistant, in which case, round towards the even neighbor.
  • IntegerToLocalizedStringTransformer::ROUND_HALFUP Rounding mode to round towards “nearest neighbor” unless both neighbors are equidistant, in which case round up.


type: integer default: false

The value set as the NumberFormatter::GROUPING_USED attribute when using the PHP NumberFormatter class.

Inherited Options

These options inherit from the field type:


type: Boolean default: true

If true, an HTML5 required attribute will be rendered. The corresponding label will also render with a required class.

This is superficial and independent from validation. At best, if you let Symfony guess your field type, then the value of this option will be guessed from your validation information.


type: string default: The label is “guessed” from the field name

Sets the label that will be used when rendering the field. The label can also be directly set inside the template:

{{ render_label(, 'Your name') }}


type: Boolean default: false

If this option is true, the field will be rendered with the disabled attribute so that the field is not editable.


type: Boolean default: false

If true, any errors for this field will be passed to the parent field or form. For example, if set to true on a normal field, any errors for that field will be attached to the main form, not to the specific field.
