my currrent output field is 1610.66 but i want as 1,610.66 ... Need a comma for thousands.. how to get that?
ToString function can do it.
@sparksun's solution works really well if you want the output to be forced to be a string - otherwise if you just want to view a comma briefly in the Results window then you can use "Show Numeric Separator" if you have a recent enough version of Alteryx.
Lastly, if you want the output to be numeric AND to still show the comma, that will have to be done in the platform itself. For example, you'd save the format in Excel and then "Preserve Formatting on Overwrite", specifying a range as well.
ToString([Field],2,",")
will work
this works for any number.
