The floor function also called the greatest integer function or integer value spanier and oldham 1987 gives the largest integer less than or equal to the name and symbol for the floor function were coined by k.

In this article we are going to learn about the floor and ceil functions of math h header file in c language and use them with help of their examples.

Floor math provides explicit support for rounding negative numbers toward zero away from zero floor math appears to use the absolute value of the significance argument. Definite integrals and sums involving the floor function are quite common in problems and applications. Because floor is a static method of math you always use it as math floor rather than as a method of a math object you created math is not a constructor. Some say int 3 65 4 the same as the floor function.

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. Iverson graham et al. The floor math function differs from the floor function in these ways. This kind of rounding is sometimes called rounding toward negative infinity.

The following example illustrates the math floor double method and contrasts it with the ceiling double method. A foundation for computer science addison wesley 1990 a2 s. For example and while. Int limits 0 infty lfloor x rfloor e x dx.

Floor math provides a default significance of 1 rounding to nearest integer. Double values 7 03 7 64 0 12 0 12. The behavior of this method follows ieee standard 754 section 4. The int function short for integer is like the floor function but some calculators and computer programs show different results when given negative numbers.
