Question 270861
Since it's an integer, just check the powers of 2 and check for a match.
0 1
1 2
2 4
3 8
4 16
5 32
6 64 That's it
So {{{log(2,64) = 6}}}
------------------------
Had it not been an integer:
log(64)/log(2) = 6
That always works, even for non-integers.
eg, {{{log(2,63)}}}
log(63)/log(2) =~ 5.9772799
{{{2^5.9772799 = 63}}}
