Question: I know that we can extract an integer value from a string using

```
var x = "> 1";
x = parseInt(x.match(/\d+/)[0], 10));

```

How do I get a float value from a string

example: `var x = "> 1.1"`

I know we can just use `x.substring(2);`

But for a more generic solution? since the above will not give the accurate result for 

```
var x = "1.1"

```

So what is the best way to extract the float value `1.1` from 

```
var x = "> 1.1"

```

Answer: 
Use `parseFloat` and a regular expression that matches a number with optional decimals and minus sign.

```
var f = parseFloat(x.match(/-?(?:\d+(?:\.\d*)?|\.\d+)/)[0]);

```
You can try the following one to extract only numbers like floating or integer as an array as many as you want using the match function.

```
str = 'On schedule: 3243.8 miles away (4491 minutes)';
values = str.match(/[0-9.]+/g); //=> ["3243.8", "4491"]

```
