javascript - parseFloat returns NaN -

i'm trying rid of currency sign in order calculate new price using parsefloat, returns nan reason.

var priceperuser = "£19.99"; priceperuser = parsefloat(priceperuser) * 3; console.log(priceperuser); //returns nan 

parsefloat() work on string until finds non-numeric value. £ first character, hence there no number parse. need remove before call parsefloat():

var priceperuser = "£19.99"; priceperuser = parsefloat(priceperuser.replace('£', '')) * 3; console.log(priceperuser); 

if require 2dp precision, use tofixed(2):

console.log(priceperuser.tofixed(2));
