I got in trouble in my project about adding two numbers.  
I found this: 0.1 + 0.2 = 0.300000000…0004 and 0.1 + 0.7 = 0.79999999999999

you are trying to add two text values. try converting them to numbers (for example, add zero), and then work with numbers …

@sewar meant that you can convert the text input to numeric values by adding zero (or multiplying by one). This is sometimes necessary when text is used in calculations. It looks like this:

However, I tried this with your setup and it still produced the long digit values.

as an option - you can show the result of 6 characters and then there will be no error
