i fixed the "e" problem by using digits

getcontext().prec=20
it works fine but in my algoritm it was checking the answers by their lenght so this created a new problem by giving all the answers with 20 digits. I might fix this but i have searched for 4 hours just how to get rid of 'e' . i think there must be a easier way to do this.
