Thanks kr - I tested your suggestion on my machine. Avoiding Math.Pow was indeed quicker - about 3 times for integers, twice as fast for doubles.

Your solution works fine but it works rather slow....

Your solution works fine but it works rather slow. On the following website I found methods that work about 5 times faster: http://cboard.cprogramming.com/csharp-programming/75260-return-value-nearest-100-a.html

I think you should avoid usage of Math.Pow...

If you need only number why not to use smth like. Only need to check that result value will not overflow int.maxValue

int mod = value % 1000;
if(mod>0)
{
value += 1000 - rest;
}
