[quote userid="274702" url="~/discussions/f/general/38877/decimal-calculation/147072"]Dot vs. comma decimal separator is defined by the user language.[/quote]

I think the point is, you only get separators when displaying text ("1,000,000", etc).

Sorry, I didn't understand.

The amount will be entered in the text box.

To display, using fixed(amount, 2, false) in the value parameter of the text box.

We should display the user-entered amount separated by commas, so we used the text box to display the user-entered number using fixed.

No. fixed returns a string, not a decimal. The only correct way to reduce the number of decimal digits is by rounding.

My next question: Why do you use a text field in the first place?

Since it is a textbox field, the user can enter multiple digits after the decimal, and I need to save the number with precision 2.

To save the values in the local variable/cdt decimal field fixed(<<input value>>, 2) is the correct choice?

Computers represent decimal number with a limited precision. In your case, trying to convert between text and decimal multiple times does not help either.

Fixed should only be used to display a value to the user as it returns a string.
