BaseConvert plug-in

From NSIS Wiki

Author: Zenpoy (talk, contrib)


This plug-in is based on the source code on CodeProject.

To quote the original article:

The algorithm can convert a positive integer number, potentially thousands of digits long between any bases in the range from 2 to 36, including but not limited to binary, octal, decimal, hexadecimal.

Questions, comments, and bugs can be posted on the forum.
