Amazing feedback, guys ! Itīs a pleasure to help a friend as well as to do a "brain exercise".
@Jorel
Sorry for my late feedback (I was in my work !
). In final step of calculations I make a mistake, sorry !
I forgot of
sqrt (which means
"square root" ...
By the way, I agree that some steps omissions in the calculation to become the result unclear. So, fixing the error, we have
Code:
a% = [ 1 - sqrt[(Size of Target DVD - Size of Audio DVD)/(Size of Source DVD - Size of Audio DVD)] ] x 100
a% is the percentage which will be applied in each pass from two ones. You pay attention that result is
general one and depends of
size of your source DVD ,
size of your target DVD e
size of DVD audio (source).
So, I get the data that you provide which were the following:
Code:
Size of source DVD = 7976 MB
Size of target DVD = 4464 MB
Size of audio DVD = 475 MB
So, we have to perform:
7976 - 475 = 7501 (size diference between DVD source and DVD audio)
4464 - 475 = 3988 (size diference between DVD target and DVD audio)
So, we have to perform
3989/7501; after to
extract to square root of that result and then the one is deduct from
1; finally we multiply for 100 e then we will get the percentage !
In the present case, it will be:
