I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

Have you looked at NumberForm?

comment Permanently rounding numbers/values to a given number of significant figures
In my opinion your question would be much improved if you were to edit out the ranting and just present the numerics problem you want to address.
