Formulas are used to perform mathematical operations within app. It works at the FRONT of you app. Mobsted platform supports all arithmetical math functions and all MathJS formulas.
Where Math is available
You can use Math formulas at ANY ELEMENT on the platform. For example - on Screens, in Elements Values or backend names, in Variables, on Elements hide/show conditions and in Actions, in Custom JS, basically anywhere where the platform need to work on any kind of text field.
...
For Functions wrap data source into additional parentecies, just like with Functions in spreadsheets, for example the square root funtion:
=( sqrt(4) )=
Referencing data in Math
You can include Hashtags references to perform calculations with any data from any part of platform and build math expressions with it. For example:
=( #hashtag1# + #hashtag2# )= OR =( 3 + #hashtag2# )=
Sample Use case
In the example below you can see that the Text field with the Formula has the =(........)= notation sum of two fields is dynamically updated when we enter the new value to the one of the inputs.
Examples of Available Math Formulas
The rest can be found here - https://mathjs.org/docs/index.html
Action | Example |
SUM / Multiply | =( #hashtag1# + #hashtag2# )= / =( 5 * 2 )= |
Subtract / Divide | =( #hashtag1# - #hashtag2# )= / =( 6 / 2 )= |
Modulus | =( #hashtag1# % #hashtag2# )= |
Exponentiation | =( #hashtag1# - #hashtag2# )= ^ =( #hashtag1# / #hashtag2# )= |
Square root | =( sqrt(#hashtag1#) )= |
Factorial | =( #hashtag1#! )= |
