Formula Functions

This page documents the list of functions that are supported in Formula Engine. Each of the functions provides examples of how that function can be used. Those examples can be inline edited to try out variations. You also try out any of these functions in Formula Playground.

Go through the Video Guide below for a short introduction on how to read this page. If you think any other formula is helpful, please let us know at support@datasert.com

info

All string functions are case-insensitive
While most of the functions are null tolerant, if there is a ? after parameter name, then it means that function is designed to handle the absence of that parameter
If there is a ... before a parameter name, it means you can specify multiple parameters separated by a comma

abbr

abbr(input, length)

Abbreviates the input to length chars.

If input is null, then returns as is
If input is string, then abbreviates the input. If string length is same or shorter than length then returns the input as is.
If input is longer than length, then truncates to length with ... appended.

Expression	Result
`abbr('Boing Inc', 5)`✏️	`Bo...`
`abbr('Boing Inc', 10)`✏️	`Boing Inc`

abs

abs(input)

Returns the absolute value of the input

If input is null, then returns the input as is
If input is a -ve number, then returns +ve of that number
If input is a +ve number, then returns the number as is
If input is not number, then return the input as is

Expression	Result
`abs(-10)`✏️	`10`
`abs(-10.45)`✏️	`10.45`

add

add(val: any, valToBeAdded: any): any

Adds valToBeAdded to val. The behavior depends on the type of val.

If val is an array, it concatenates valToBeAdded to val.
Otherwise, adds valToBeAdded to val using a standard addition operation.

Expression	Result
`add([1, 2, 3], 4)`✏️	`[1,2,3,4]`

If min is null, treats it as negative infinity
If max is null, treats it as positive infinity
If no bucket matches, returns the defaultVal
Supports both numeric and string ranges
