167.4 and 167.462 which one is greater

167.462 because it acts a bit like surnames in a register like if you say your surname was Hayward and there was someone's surname Heaton there both h but then when you look at the next letter A is before E so if the number is 167 and your other number is 167 then look at the decimal and they are both 4 then look at the next number which is bigger than 4 so it is closer to 5 than 4 if that helps
