Project: Standard Deviation
Write a filter program that accepts text representations of floating point values on the standard input, one per line. The program should then compute the standard deviation of a list of floating point values. Finally the program should simply output the value of the standard deviation to 16 decimal places on a single line so that it can easily be used by other programs.
