WebSep 15, 2010 · If all you need is the integer part of log base 2 of a floating point number, extracting the exponent is pretty efficient: log2int_slow = int(math.floor(math.log(x, 2.0))) # these give the log2int_fast = math.frexp(x)[1] - 1 # same result Python frexp() calls the C function frexp() which just grabs and tweaks the exponent.
