Facing issue while creating a basic calculator using Figma variables

Hey @Shraddha_Poddar – can you send a copy of your calculator prototype over to our support team? I think this would be better addressed by them. They can check the connections to see where things may be breaking.

You can file a ticket here: https://help.figma.com/hc/en-us/requests/new?ticket_form_id=360001744374

Thanks @ksn

I have raised a ticket with the above issue.
Looking forward to hearing soon!

The unexpected results in your Figma calculator (like 77777776, -2147483648) are likely due to integer overflow. When you keep multiplying the result by 10 and adding digits (e.g., Result * 10 + 7), the number quickly grows beyond the 32-bit integer limit (2,147,483,647), causing it to wrap into negative values. To fix this, treat the result as a string and use string concatenation (e.g., Result + "7") instead of arithmetic. This approach also mimics how real calculators display inputs. If you're building tools like this, you might enjoy designing a CGPA calculator as well—similar logic, but more academic use. Let me know if you'd like help with that too!

While experimenting with Figma variables to create a basic calculator UI, I ran into unexpected issues — especially when trying to handle input changes and dynamic values. It's a great tool for design logic, but still not a full replacement for JavaScript-based logic.

This made me appreciate how tools like the LIC Maturity Calculator handle complex calculations so smoothly behind the scenes. Whether you're designing or calculating, it’s all about getting the logic right!
