Question

I have a string, where I need to parse it as a float, but first I need to replace it, if it is not a number (an integer or a float), so I am trying to create an regular expression to do it

My tries results in NaN

One of my best tries is

var $replace = $text.replace(/^[^d.]*/, '');
var $float = parseFloat($replace);

Can anybody tell me, what I am doing wrong?

Answer 1

if (! isNaN($text))
  $float = parseFloat($text);
else
  $float = 0; // or whatever
