public class TextFormat
extends Object

Class to provide formating routines for integers and doubles. Calling the format(int) method with a value of 3.1415926536 yields the following output:

   format(val)                                     >3.14159<
   format(val, 3.e-8)                              >3.14159265<
   format(val,7)                                   >3.1415927<
   format(val,13, 5)                               >      3.14159<
   format(val,13, 5, false)                        >      3.14159<
   format(val,18,6,true,true,true,false)           >3.1415930000000000<
   format(val,18,6, false,true, false, false)      >00000000003.141593<
   format(val,18,6, false,true, false, true)       >+0000000003.141593<
   format(val,18,0,true,false,false,false,false)   >                 3<
