Changing a value (string) to an integer

Hi all,

I've read multiple articles on this one, but I cannot get it right.

In Lists I have a calculated column (when I put in the number 10 in a different column, it is multiplied by 28). Although I've set the outcome to number, apparently in Power Automate it still turns out as a string. When I use the value in a 'Populate a Word document' - it gives me back the calculated number (280 in this case), but it adds 12 zeros after the decimal point (280.000000000000).

I just want the number 280 (or another calculated number) in the Word document 😉

I've put in an action Format Number, but that gives me the error: 'The template language function 'formatNumber' expects its first parameter to be an integer or a decimal number. The provided value is of type 'String'.

So I tried something with Initialize variables and Compose (expression int(items('Apply_to_each')['ColumnName'])) - but I don't have an apply to each there. Tried to insert an apply to each, adjust the expression, I'm lost now....

Hope you can help, thanks a lot in advance 🙂

Re: Changing a value (string) to an integer

Thank you so much @Matthy79! I deleted the 'Format number' action and put in the expression directly in 'Populate a Word document' and now it works beautifully 😇

Thanks again for your quick help!

Re: Changing a value (string) to an integer

Hello @Femke1

You didn't use the expression but an action to format a number. This way it works a little different. Into the first field you have to put a valid number. In your case it would be "int(outputs('Create_item_-_NAME-OF-THE-ACTION-ABOVE')?['body/NAME-OF-THE-COLUMN'])". So without the formatNumber around.

After that action works fine you can use dynamic content to work with it later.

The expression you posted can be used directly inside another action ("Populate a word template" for example).

Re: Changing a value (string) to an integer

Hi Matthy79,

Thanks for your suggestion! Much appreciated 🙏

Don't know if I understand you correctly, but what I've tried, gives me the same error:

I used the expression:
formatNumber(int(outputs('Create_item_-_NAME-OF-THE-ACTION-ABOVE')?['body/NAME-OF-THE-COLUMN']), '0')

Do you have a suggestion of what I'm missing?

Thanks a lot!

Hello @Femke1

You don't need a new variable. In the expression where you get the error "The template language function 'formatNumber' expects its first parameter to be an integer or a decimal number" just add another expression. For example if it looks like this:

formatNumber(yourStringNumber, '0')

change it to:

formatNumber(int(yourStringNumber), '0')
