In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.

Floor int c. Float ceil float x. Include math h applies to. Round down value rounds x downward returning the largest integral value that is not greater than x. If arg has type long double floorl is called.

The floor function returns the largest possible integer value which is equal to the value or smaller than that. Returns the largest integer that is smaller than or equal to x i e. The value to round down to the nearest integer. It takes single value whoes floor value is to be calculated.

C floor the floor function in c returns the largest possible integer value which is less than or equal to the given argument. Double ceil t x. This function is also declared in cmath header file in c language. For information and restrictions about using the sse2 implementation see set sse2 enable.

Long double floor long double x. In a c program unless you re using the tgmath h macro to call this function floor always takes and returns. Long double ceil long double x. The floor function returns the largest integer that is smaller than or equal to x.

In the c language the required header for the floor function is. Double ceil double x. Rounds downs the nearest integer. Otherwise if arg has integer type or the type double floor is called.

Floor has an implementation that uses streaming simd extensions 2 sse2. 1 3 computes the largest integer value not greater than arg. Double floor double x. Here x is the floating point value.

However the result may overflow any integer type including std intmax t when stored in an integer variable. C allows overloading so you can call overloads of floor that take and return float and long double values.
