How to Use Decimal Points in Acrobat DC Number Fields
Question details
The user wants to configure PDF form number fields to display a decimal point instead of a comma.
- Product
- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Creating or filling out interactive PDF forms that require specific numerical and decimal formatting.
- Observed behavior
- The number fields currently default to using a comma instead of a period for decimal separators.
Ensure you have editing permissions or the master file for the PDF form, as changing field properties requires administrative access. Close any active instances of the form in standard viewer mode before making structural modifications.
Configure Number Format via Field Properties
The most direct way to change the decimal separator is by adjusting the specific format settings of the number field inside your PDF editor.
By directly modifying the form field's formatting options, you can force the document to always use a decimal point, regardless of the system settings of the person filling out the form.
Open the PDF form in Adobe Acrobat DC and select the 'Prepare Form' tool from the right-hand pane.
Right-click the specific number field you want to modify and select 'Properties' from the context menu.
Click on the 'Format' tab located at the top of the Properties dialog box.
Under 'Select format category', choose 'Number'. In the formatting options that appear below, find the 'Decimal separator' dropdown and set it to a period (decimal point) instead of a comma.
Click 'Close' to save the properties, then click 'Preview' at the top right to test the field and ensure the decimal point is applied correctly.
Modify Operating System Regional Settings
Acrobat often inherits number formatting from your computer's OS locale. Changing your system's regional settings can fix default comma formatting globally.

Frequently Asked Questions
Why does my PDF form use a comma instead of a decimal point by default?
PDF applications often default to the regional and language settings of your operating system. In many European and South American regions, the standard decimal separator is a comma, which the software automatically adopts unless instructed otherwise.
Will changing my OS regional settings affect other applications?
Yes, modifying the decimal symbol in your computer's regional settings will change how numbers are formatted in all software that relies on the system locale, including spreadsheet programs and calculators.
Does the decimal formatting carry over if I send the PDF to someone in another country?
If you hardcode the decimal separator to a period in the field's Format Properties, it will display correctly for other users. However, if the field format is left on generic system defaults, it may switch to a comma depending on the recipient's local computer settings.
Can I prevent users from typing letters into a number field?
Yes. When you set the field format category to 'Number' in the Properties menu, the PDF viewer will automatically restrict inputs to numerical characters, decimal points, and minus signs, rejecting letters automatically.
