Conversion of numbers from one form to other : I have a data frame "df" with a column "Amount", which contains values in millions like 2.3, 17, 1.47 and so on. I want to create a new column "Amount1" in "df" which converts each value in "Amount" to the form like 2300000, 17000000, 1470000 and so on. How would I accomplish this task?
