SUMMARY

The discussion centers on the search for a specific inverse calculator tool that provides complex representations of decimal numbers. The user initially references the ISC project but clarifies that the desired tool is a downloadable console application, distinct from existing online tools. The tool identified is RIES, developed by Robert Munafo, which offers functionality for approximating numbers through increasingly complex representations. This tool is noted for its unique approach compared to other resources like Maple's gfun.

PREREQUISITES
  • Understanding of inverse calculations and numerical representations.
  • Familiarity with console applications and source code usage.
  • Basic knowledge of mathematical approximation techniques.
  • Awareness of existing tools like ISC and Maple's gfun.
NEXT STEPS
  • Explore the RIES tool by Robert Munafo for practical applications in number representation.
  • Investigate the ISC project for additional resources on inverse calculations.
  • Learn about mathematical approximation techniques to enhance understanding of complex representations.
  • Research other tools similar to Maple's gfun for comparative analysis.
USEFUL FOR

Mathematicians, software developers, and researchers interested in numerical analysis and complex number representations will benefit from this discussion.

I'm looking for a particular tool I once came across. It took a decimal number as input and tried to give some calculation which would return that number as the result. I'm familiar with http://oldweb.cecm.sfu.ca/projects/ISC/ISCmain.html, but neither of these is the tool I'm looking for. These tools are essentially lookups on large tables; the one I remember was a program that found increasingly-complex representations of the number that more closely aproximated it. Plouffe's tools are online; this one was downloadable (a console application, with source code I think). The documentation, such as it was, mentioned the ISC and explained how the two were different.

Does anyone know what I'm talking about? Failing that, does anyone know of something similar?

Maple's gfun is similar, but doesn't quite fit the description.
 
I finally found it, so I thought I'd mention it here in case someone else wanted to use it. It's RIES, by Robert Munafo:
