Has anyone used the format() function in the expression builder?
The definition states it require arguments. just playing around with it but cant find too much on this function so i am not sure on its actual use/output/argument requirements.
This is the help text in Field calculator:
function format Format a string using supplied arguments. Syntax format(string, arg1, arg2, ...) Arguments string A string with place holders for the arguments. Use %1, %2, etc for placeholders. Placeholders can be repeated. arg any type. Any number of arguments. Examples format('This %1 a %2','is', 'test') → 'This is a test'
