Issue in showing Negative numbers and floating point numbers

Hi,
I used progressed.io in one of my markdown scripts. Its nice, but its not showing negative or floating point numbers.

progressed.io does not support negative or floating point numbers. You may open a PR for this.

Floating point numbers are exactly what I need. I'll definitely get my hands dirty with this when I have some free time, especially considering how there's no one around to do it anyway.
