Number is an element that takes string type data and converts it to rational numbers, including:

  • Negative numbers
  • Decimal numbers
  • Natural numbers

Decimal numbers are written with a point instead of comma.

You can customize number elements using their options.

Functional Characteristics

This element accepts only number type of data. Thats why you can use its field values fo different calculations. Also, thanks to the various settings, you can set the format of the input data. That is, when the user enters some data, they will be displayed in the configured format, for example, monetary.

Value Format

Despite number is a string, it accepts any letters and signs except minus and dot.

    "field_value": "-3.00"

That is because of their conversion to a numeric data type.

This gh-element has many options that allow you to customize the numbers to your liking. As most of others elements, number has two types of options.

Field Settings
