Hi all,

i'm not a mathematician therefore I need help! is there a calculation that determines how many times a smaller number has to be doubled to achieve a larger number? also will it work where doubling a number doesn't exactly fit into the larger number?

for example I know that 10 doubled three times equals 80 but is there a calculation where we know of 10 & 80 but it calculates that 10 needs to be calculated 3 times?

Cheers for any help!
