Round numbers?

Hello, I have a list of numbers that can be in format like:

Code:

---

8.8458e-119   
1.06542e-52
2.68e-36
2.91405e-35
0.0190644
0.0205511
0.004

---

Is there something you can suggest me that I use to have some more "elegance" appearance, i.e:

Code:

---

8.84e-119   
1.06e-52
2.68e-36
2.91e-35
0.019
0.02
0.004

---

? Note that I have all these number formats and I want to use a command that could apply to all of them.

You haven't mentioned what server-side language you are using. If it is PHP, have you tried using sprintf()?
