In the c programming language the floor function returns the largest integer that is smaller than or equal to x ie. It takes single value whoes floor value is to be calculated.

This function is defined in cmath header file. Returns the largest integer that is smaller than or equal to x i e. The ceiling function is usually denoted by ceil x or less commonly ceiling x in non apl computer languages that have a notation for this function.

The datatype of variable should be double float long double only. The floor function returns the largest possible integer value which is equal to the value or smaller than that. Header tgmath h provides a type generic macro version of this function. In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.

You can store the result and use it in whichever way you want to. C library function ceil the c library function double ceil double x returns the smallest integer value greater than or equal to x.

The ceil function takes a single argument and returns a value of type int. The j programming language a follow on to apl that is designed to use standard keyboard symbols uses.
