Detailed Description

Class representing formatting options for output (stearming) of doubles.

It handles two characteristics, the precision (number of digits) and width of the output, where the latter can also be left calculated automatically by FormDouble::FormDouble(int)

Generic overall precision accessible throughout the framework.

Can be set by reading in any variable of class FormDouble from the command line through the parameter-bundle.
