I'm trying to get rid of currency sign in order to calculate new price using parseFloat, but it returns nan for some reason.
var pricePerUser = £19.99;
pricePerUser = parseFloat(pricePerUser) * 3;
console.log(pricePerUser); //Returns NaN
parseFloat() will parse each character of a string until it finds a non-numeric value. The £ is the first character, hence it finds no number to parse. You need to remove that before you call parseFloat():
var pricePerUser = "£19.99";
pricePerUser = parseFloat(pricePerUser.replace('£', '')) * 3;
console.log(pricePerUser);
Could you suggest how I can print out numbers like 19.90 instead of 19.9 in this case?
If you require 2DP precision use toFixed(2) when displaying the output to the UI:
console.log(pricePerUser.toFixed(2));
