Hi all,

heres a quick one for you,
I have a series of data that I am using dictionaries to build 
histograms for. I'd like to round the data to the nearest 10, i.e if 
the value is 15.34  should we round down to 10? and conversely rounding 
say 19.30 to 20. I'm thinking 15.5 and above would round up. Can anyone 
point me a at a quick and painless way of achieving this?

  cheers

Kim
