After adding this validator, expressions can be used in forms.

For example:

  • 12.80 + 3.50 * 2 - valid expression. Result: 19.8.
  • (2 + 2) * 2 - valid expression. Result: 8.
  • (2 + 2 - invalid expression.

This validator checks an expression and saves a result. And it can be used for currency fields or any numeric fields.
