Largest 2^n less than x?
Other than iterating n and testing against x, is there a particular method in SAGE to find the largest 2^n less than a specified integer?
Thanks CL

What about using logarithms and rounding from below using the floor() function ?
Another possibility could be to look at the size of the binary representation of your integer a by using a.binary() or a.bits().
