Rounding Down

[Tom England]

I am creating a DB to calculate tax on cars related to their CO2 emissions. I have a field "CO2 emissions" - I then want another field "CO2 Emissions Round" to round this figure DOWN to the nearest 5.

So CO2 Emissions = 194 would be rounded down to 190

Can anyone help??

Thanks
