Oliver, There some brackets missing. Please try Position[#,Max[#]]&[list] Position[#,Max[#],{1},1]&[list] Will give the first position of the maximum. If this doesn't work please post examples. -- Allan --------------------- Allan Hayes Mathematica Training and Consulting Leicester UK www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565 "Oliver Friedrich" <oliver.friedrich at tz-mikroelektronik.de> wrote in message news:9m27in$gqd$1 at smc.vnet.net... > Hi, > > what's the best way to get the position of the greatest number in list of > reals?
