Floor and ceiling function in discrete maths.

The best strategy is to break up the interval of integration or summation into pieces on which the floor function is constant. This set of discrete mathematics multiple choice questions answers mcqs focuses on floor and ceiling function. If this set is countable prove it by proposing a bijection a oneto one and onto function between this set and the set of positive integers z. A floor function map a real number to a smallest previous integer b greatest previous integer c smallest following integer d none of the mentioned view answer.

In addition to the arithmetic operators you are allowed to use floor and ceiling functions. Int limits 0 infty lfloor x rfloor e x dx. 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. Since we know that x n if and only if x n n integer.
