This is not an ordinary rounding issue. Here's what I need to do. I have to round any number up to the nearest 25,000 increment.

For example:

124,698 would need to round to 125,000
126,125 would need to round to 150,000
1,278,189 would need to round to 1,300,000

Anyone know of a mathematical formula for doing this? Or any good ideas as to how to accomplish this? THANKS!
