I want the result of
1200000000*0.001 to be
But Mathematica's output is in the form of scientific counting.
How can I make numbers larger than
1.*10^-8 and smaller than
1.* 10^9 output by scientific counting every time in Mathematica?
For example, for the number
1.231456785*10^6, I want the output to be
1231456.785 every time. It's better to save the settings to the configuration file.
