RVal is a program for Electronic Engineers and hobbyists. It will find the nearest preferred resistor values satisfying certain criteria or all within a given tolerance, in whichever range of preferred values the user selects. All the standard value ranges are supported; they are E6, E12, E24, E48, E96 and E192 and the user can add their own ranges. Preferred values can be selected according to the following criteria:

* The nearest preferred value to that specified.

* The pair of preferred values having the closest approximation to the required Ratio.

* The pair of preferred values having the closest approximation to the required Difference.

* Pairs of preferred values which, when placed in series or parallel provide the closest approximation to the required value.

* The preferred value required in parallel with an existing value to provide the closest approximation to the required value.

The program's output can be printed, saved or appended to a text file or copied (in part or in full) to the clipboard. RVal also includes the facility to output a list of the values in the selected range. Clipboard or file contents are also suitable for import into a spreadsheet or similar program.
