Regular expression Syntax in Ninox

I asked Chat GPT "regular expression for eliminating numbers after a comma in Ninox database", and I believe the answer is wrong. I'm familiar with regular expressions; I usually apply them on Numbers and Excel but I do not know how to apply them on Ninox.

My (failed) procedure has been as follows:

1) I'm on a table and I'm applying a "Formula" with the button "fx Formula"

2) I then get the pop-up screen that lets me give a name to the field, give it some style, apply an "On click" rule, etc.

3= I then click on the "Formula" field's button and, considering that "PRICE" is the name of a field, I type the following:

let cleanedText := replaceAll(PREU, ",.*$", "");
cleanedText

This syntax is completely wrong. I have tried other things like:

extractx(PRICE),\d+

I could not find the syntax for Ninox at all.

Can anyone help?

Hi videodossier, I hope I got you right with what you would like to achieve. Assuming that the PRICE field is a number field (works also with fx field) you just need to click here at Zahlenformat, then a window pops up where you can define what should happen after the comma.

The solution for your problem with regular expression is (brain used)

extractx(TEXT, "\d+(?=,\d+)")

or

replacex(TEXT, ",\d+")

but the idea from Kruna is better. Mirko

Hello,

The solution from Kruna does not suit my needs because of what I want to do. I nevertheless tried it and I thank you very much, Kruna.

I actually want to take what is behind the coma on the value of a price field. So, if the price is 72 I want a field with a formula that will be automatically filled with "0". And if the price is 72,35 the field will be filled with "35".

I have tried, the solutions from Mirko but none of the syntax is right. I replace "TEXT" by the name of the field where the price is but it Ninox won't accept the syntax. This is what bothers me. I have not found clear documentation on how to apply RegEx syntax in the Formula's Text environment.

Any more ideas? Thank you so much, Mirko!

The problem could be the field types. Regex in Ninox is for text() and your field could be a number field. So the value must first be converted. My code is also wrong, because I assumed that you need the number before the decimal point. Try this. Mirko

item(split(text(PREU), ","), 1)

or

replacex(text(PREU), "\d+,", "")

I read your text again. If your field is a number field and reflects a price, then it should work that way.

(PRICE * 100) % 100

This will give you the decimal value after the decimal point, i.e. the cent amount

  Hello, Mirko. I do not exactly understand why this is working. But it perfectly works. Thank you very much. I'll try to study about how this % 100 is actually working.
  
  Thanks so much; really, thanks so much!

  % is an operator called modulo, like plus or minus. It gives you the remainder after a division of integers. Since the decimal places in prices are never more than two, I multiply by 100 beforehand, i.e. 12.45 becomes 1245 and then I divide (modulo) by 100 and the remainder is 45. Mirko

ChatGPT is not able to give the right answer for NINOX Script. It always gives you javascript or something like this...
