Although you will mostly use Integer and float numbers in your program. Python float() is an inbuilt function that converts String to Float. As you can see num1 variable is of type string so Python tries to concatenate num2 to num1 rather than adding them. Unlike bin() function of Python, it can convert floating-point numbers also. First we take the integer part from the floating point value and convert it to binary then take fractional part and convert it to binary form and lastly combining both. This might be required sometimes where we want to concatenate float values. We can use complex() function to convert an int or float to the complex number, the imaginary part will be 0j.
