Where is the command to set number format in the latest version of Numbers?

I can't believe that Numbers seems to make it easy to do something stupid like turn a cell pink, but that I cannot find ANYWHERE the simple icons/commands to set the various important number formats. Scientific notation, Currency, fixed decimals. What am I missing here? I'm remembering Appleworks 6, whose spreadsheets allowed a halfway intelligent user to get actual work done. Help will be highly appreciated.
