Teacher asked me some time ago if there´s a way for this:
I have this: 500000000000000000000
how can I express this in a form of power of a number (something to power of something)? Note that I don´t want to get the exact result, I want to only get the RANGE 5xxxxxxxxxxxxxxxxxxxx.
Well, you can express it in any number of ways:
500 000 000 000 000 000 000 =5E20 or 5 x 10^20 or 6^26.6 .......etc.
thanks, but this isn´t exactly I´m looking for. I mean this:
how can I quickly compute which power gives me 5XXXXXXXXXXXXXXXXXXXX? X-random value, but that doesn´t matter - I want to give the length.
I am not sure ywhat you are asking.
I think you are asking for a little program to find the power when it is written in scientific notation?
How about having a counter.
1 counter c=0
2 number n=50000000000000000000000 (or whatever the original number is)
3 Test: Is the number n less than 10?
4 If yes, then n is the power and END
5 If no, then add 1 to counter
6 replace n with n divided by 10
7 Go to step 3
I have not checked my logic thoroughly but that seems like a good outling of a little program that will do this
