How can i change my calculator so the answer will be in decimals instead of exponents or fraction?
There is a misconception hiding here in your statement. A decimal result on a calculator is often no more than an approximation: Try expressing 1/3 as a finite decimal representation. So, the only exact results that you may get are those displayed as fractions and those with radicals.Now let us address your question. The calculator has a limited display capability. Any decimal result that is too small or too large to fit in the display window will automatically be displayed in scientific notation (the one with exponents).If you want exact results, you should set the Input/output to MathIO. Even then, if the expression requires more display space than is available, it will be displayed as a decimal number.

I have a lot of numbers on the starting and ending points
Hello,
Regardless of the way it looks, this huge number is just 1, written in scientific notation, with 9 decimal digits. This is due to the configuration of your calculator.
To revert to the default display mode, press [SHIFT][MODE][6:Fix] and select a number of decimal digits between 0 and 9.
If you do not like the [MathIO] (fractions, radicals) you can use the [SHIFT][MODE][2:LineIO]
Hope it helps.
