Regular expression for converting 0.085 to 0.08

Question

I am having regular expression using following code

var data = 0.085;
var output = "$"+data.toFixed(2).replace(/(\d)(?=(\d{3})+\.)/g, '$1,');
console.log(output);

The problem is that it does not round off value 0.085 to 0.08. I am allowed to use this regular expression.

So... what do you get? 0.09? That's the correct value. Why are you manipulating numbers with regex anyway? — jonrsharpe, Jan 05 '17 at 07:51
when range is 0 to 4 the value gets converted to lower value if value is greater than 6 to 10 then it get convert to upper value which is correct but here whan there is mid value 5 after any digit it it should get converted to lower value i.e 0.085 to 0.08 — amar ghodke, Jan 05 '17 at 07:56
Then why didn't you search for that? Do your research, this took me ten seconds to find: http://stackoverflow.com/q/26806234/3001761 — jonrsharpe, Jan 05 '17 at 08:07

Try this:

var data = 0.085;
var output = Math.floor(data * 100) / 100;
console.log(output)
