I want to round up any given number to the nearest set of specific values only. The values are 5,10,20,25,50,100
So if the given number is 2 it will be rounding up to 5. If it's 71.6 it will be rounding down to 50, if it's 250 it will be rounding down to 100
Anybody can give me a clue how to do that? Thanks a lot!
