Please briefly explain that the function you propose is one to one and onto. And this is the ceiling 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. One is the floor function and the other is the ceiling function for example the floor and ceiling of a decimal 3 31 are 3 and 4 respectively.

In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or. The best strategy is to break up the interval of integration or summation into pieces on which the floor function is constant. For example and while.
