In Python you can use math floor and math ceil to round a floating point number float down and up Note that math floor rounds toward negative infinity and math ceil rounds toward positive infinity Be careful when working with negative values Here s a summary of the results Round up down after the decimal point in Python math floor ceil . Note The behavior of round for floats can be surprising Notice round 2 675 2 gives 2 67 instead of the expected 2 68 This is not a bug it s a result of the fact that most decimal fractions can t be represented exactly as a float When the decimal 2 675 is converted to a binary floating point number it s again replaced with a binary approximation whose exact value is In 1st case you first cast the number to int so all digits after comma are gone then you cast again to float so for example 3 6 will result in 3 0 which is mathematically wrong Round is mathematical round cymruu Apr 27 2017 at 14 40 The round can also take a second argument for the precision That makes it different from the float int n
