1. Divide it by the unit to which it is to be rounded 2. Round it to the nearest whole number, unless it ends in exactly .5 3. If it ends in exactly .5, then round towards the nearestevenwhole number 4. Multiply it by the unit to which it is to be rounded ...
6. np.round() in Python for large arrays Let’s use np.round to compute the world population every year, rounded to the nearest million (6 zeroes). give the result (an array of 66 numbers) the name population_rounded. Your code should be very short. ...
Python's round() function uses "round half to even" as its default rounding mode when you omit the second argument. Rounding half to even (bankers’ rounding) is when a number is exactly halfway between two integers, it is rounded to the nearest even integer. This technique is useful sin...
