How can I get parseFloat to only give a one or two decimal point answer?

When i add numbers like 3.4 + 2.1 it returns 5.5000000001 . Why does it give me so many decimal places? How can i get it to only return 5.5?

Have you tried using the .toFixed() method? This method formats your number using a fixed point notation, so whatever number you call in the method will be the number of decimal places. Hope this helps

If I'm not mistaken, .toFixed() usually returns a string, so you'd need to convert it to a number again...
