The following example illustrates the math ceiling decimal method and contrasts it with the floor decimal method. 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 ceiling math function differs from the ceiling function in these ways. Floor returns number rounded down towards zero to the nearest multiple of significance. Some say int 3 65 4 the same as the floor function. Console writeline value ceiling floor n.

We can round a number upwards to the nearest integer with a ceiling function or down with a floor function. Math floor 1 8 1 0 math floor 2 0 2 0 ceil.
