Document Summary
Some process that take data as input, performs some operation on these data, and then returns different data. Are not universally useful, depends on what is put into it. Thelargestnumber = max (data), input is data , function is max () , and the output is. Thelargestnumber : the input data could consist of many numbers, but only one number comes out of the function (max value, if the input data are samples, then the output data are statistics. Logdata = ln(data: the input data can consist of one or many numbers, the output data consist of the same number of numbers, but now they have been converted into their natural logarithm. By typing = len(cell) (where cell is some cell in a spreadsheet) you can return the number of characters in the cell. Functions are often used to save time, almost every computer program has some set function available, but it can take time to learn them.
