WebAnd this is the Ceiling Function: The Ceiling Function. The "Int" Function. The "Int" function (short for "integer") is like the "Floor" function, BUT some calculators and computer programs show different results when given negative numbers: Some say int(−3.65) = −4 (the same as the Floor function) WebTypical approach. If we want to do this in C++, we can call the ceil () function, but with caution. For the example above, Note that it prints out 1, not 2! This is because a and b are int data types, so that their quotient a/b is in int and the decimal values are discarded (floored). a/b = 1 so ceil (a/b) = ceil (1) = 1.
