How can I take in a string and parse it into a float?

Question

preserveDecimal(n) preserves n's decimals (it parses n as a floating point number) and returns the parsed number:

Error: Expected '2.222' to be 2.222

I am new to coding and I have been stuck on this assignment for a while.

I get an error saying that preserveDecimal(n) is not defined. I believe I have to declare it with a function and then return it but im not sure how to set up the code — Jsk8, Dec 27 '20 at 06:49

Use the inbuilt function to pass your string to a float. It will be parsed if the string is a valid float.

let x = parseFloat(string)
