If it is a positive integer, the number of bits is related to the base-2 logarithm. You may need to experiment a bit; but I think the number of binary digits is something like: ceiling(log2(number)). Of course, Visual FoxPro doesn't have a log2() function, but that can be solved easily as ceiling(log(number) / log(2))
