How do I input a numbers with infinitely repeating digits into the calculator?
Depends on the number. If the number is, say, 0.555555555... then you can simply input 5/9 and it will display your number. However, if there are more then one digit repeating, I don't know how to help.
# of repeating digits=# of nines you put the digits over
For example, .142857142....=(142857)/(999999)=1/7
.333333333333333= 3/9=1/3
same for all repeating decimals.
