15 Σεπ 2010 · If all you need is the integer part of log base 2 of a floating point number, extracting the exponent is pretty efficient: Python frexp () calls the C function frexp () which just grabs and tweaks the exponent. Python frexp () returns a tuple (mantissa, exponent). So [1] gets the exponent part.
14 Αυγ 2024 · The logarithmic function in Python can be accessed through the math module for natural logarithms and logarithms of any base. The math.log() function returns the natural logarithm (base e ) of a number, while math.log(x, base) returns the logarithm of x to the specified base .
