Rounding Up

[solarisuser]

Hello,

I am writing code for CPU Speed detection, and then inserts it into a MySQL DB.  I have finished this part.

What I need help with:

I need to look at my speed variable, which will be something like 500, 800, or 3000.
For example, if the CPUspeed variable is set to 1700, I want it to be modified to 1800.  If its 1800, then leave it alone (or modify to 1800).  If its 1690, I want it to be 1600.
If its 3000, I want it to be 3000.  If its 3110, I want it to be 3200.

I just need it for the number, I do the Mhz and Ghz distinction later.

Thanks!
