Floor function in cpp. C allows overloading so you can call overloads of floor that take and return float and long double values. This function is defined in cmath header file. Additional overloads are provided in this header cmath for the integral types. For example and while.

Floor has an implementation that uses streaming simd extensions 2 sse2. Header tgmath h provides a type generic macro version of this function. The ceil function in c returns the smallest possible integer value which is greater than or equal to the given argument. Ceil and floor functions in c last updated.

04 04 2018 in mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer 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. 373 375 f 10 6 2 the floor functions p. 7 12 9 2 the floor functions p.

For information and restrictions about using the sse2 implementation see set sse2 enable. This function is also declared in cmath header file in c language. These overloads effectively cast x to a double before calculations defined for t being any integral type. C library function floor the c library function double floor double x returns the largest integer value less than or equal to x.

251 7 25 type generic math tgmath h p. The floor function returns the largest possible integer value which is equal to the value or smaller than that. In a c program unless you re using the tgmath h macro to call this function floor always takes and returns. This function is defined in cmath header file.

The floor function takes a single argument and returns a value of type double float or long double type. C11 standard iso iec 9899 2011.
