Calculate the difference between two strings and output the result as a decimal number

I have two fields containing string values, and I want to subtract them to get a decimal number as a result.

The values of the two fields could be 2.43 and 1.13;

Instead of splitting the strings and performing mathematical operations, I am exploring if there is an easier option. I wonder if parseFloat() is not working because one of the values is in Romanian decimal "style" (using commas instead of periods)?

Answer №1

To convert single quotes to periods, start by using a regex formula.

In this case, the variable "str" represents the value of your field.

var newStr = str.replace("'", "."); 

Next, apply ParseFloat(newStr) to complete the conversion.

Answer №2

To convert the comma to a decimal point in a string, you can use the replace method followed by parseFloat.

var x = '3,50';
var y = '4,25';

var num1 = parseFloat(x.replace(',', '.'));
var num2 = parseFloat(y.replace(',', '.'));

console.log(num1 + num2); // 7.75
console.log((num1 + num2).toFixed(2)); // 7.75
