typeinfo

Throughout the documentation we refer to to data types that  that can be used in the the expression parser and  and its functions and field codes.

Data types define what kind of data a function needs as input and what you should expect as output.

The most common data types

info

Casting (or transforming) data types is very important throughout all functions provided by JWT.

To be able to set, transform or calculate values it might be necessary to turn a text value to a number, a number or a timestamp to a text, and even individual text or number values to a list.

The following functions will help you to achieve that.

tip

If you need to "flatten" the list, or simply convert it to a text, to be written into any field, comment, etc., make sure to have a look at the toString() function!

Automatic casting from Number to Text-String

UI Text Box
typetip

Whenever you write a numeric term at the right-hand side of concat operator + or a comparison operator like = , and the left-hand side is occupied by a text-string term, the parser will automatically transform the right-hand side term into a string

  • + (string concat): "His age is " + 30 is equivalent to "His age is " + toString(30)
    • = (any comparison operator): "30" = 30 is equivalent to "30" = toString(30)
