Detailed Description

Simple handling of Units.

Unit stores factor and symbol, and a precision value for printing. form builds a string from a value according to the format specification.

 static const Unit B( 1, "B", 0 );
 static const Unit K( 1024, "K", 1 );
 static const Unit M( 1048576, "M", 1 );
 static const Unit G( 1073741824, "G", 2 );
