Scientific notation for large numbers

So after being on break and being able to just spend tons of time on it, I was able to find a way to make this work using exponents.(IE 1.23E4) I had to delve into loge nodes with a power nodes but was able to figure it out. Now for the K, mil, bil, tril, etc that’s another story but for now it works perfect and I thank you for all your time and help. Also I didn’t want to just leave you hanging on my progress.
