![]() There is no difference between the two functions when applied to floats. Print("unc(" + str(x) + "): " + str(unc(x)))Ĭompare the above values to the values given by int(): for x in lst: If you write a number x as a decimal, then unc() returns the integer part to the left of the decimal point. The unc() method does the same thing as int() applied to floats. (Unlike ⌈⋅⌉ and ⌊⋅⌋, there isn’t a standard way of writing the truncation function.) The truncation function takes a real number x and returns its integer part n. If we phrase this in terms of the integer and fractional part from before, we get If x is an integer, then its ceil is just itself. ![]() On the other hand, if x=−9.1, then the smallest integer greater than x is −9, so ⌈x⌉=−9. the smallest integer greater than x.įor instance, if x=9.1, then the ceil of x is just 10. Just as the floor function is the real number x rounded down, ⌈x⌉ is just x “rounded up”, i.e. Next we will look at the ceil function ⌈⋅⌉. However, they return different results when we look at negative non-integers: print(int(-7.12)) Integer division by 1 returns the same value as math.floor() converted to floating point. For positive integers, int() returns the same value as math.floor(). Two other basic functions in Python are int() and // ( integer division). ![]()
