[ decimal ]

Type

[Decimal] casts a value to data type decimal. The following rules apply when performing this conversion.

  • Integer values are cast to their decimal equivalent.
  • String values that contain only a decimal or integer representation are cast to the decimal equivalent.
  • Null values are cast to 0.

It is not possible to use this method to cast values of types map or array.

Examples

To cast a value to type decimal:

Use the [decimal] type. Values retrieved from an HTML form or URL using [Action_Param] are always of data type string. It is necessary to cast these values to type decimal if they are to be used in a mathematical expression using symbols.

The following example adds the values for two [Action_Param] methods using the math symbol +, where the submitted values for Price and Shipping are '10' and '2.50', respectively.

Code

decimal(action_param('Price')) + decimal(action_param('Shipping'))

Result

12.500000
