Because c allows overloading you can call overloads of round that take and return float and long double values.

Floor vs round c. How can i round a number to celing or floor upto 2 decimal places. C round the round function in c returns the integral value that is nearest to the argument with halfway cases rounded away from zero. 3 ceil is. In a c program unless you re using the tgmath h macro to call this function round always takes and returns a double.

Header tgmath h provides a type generic macro version of this function. Typing floor gives the following floor takes a single numeric argument x and returns a numeric vector containing the largest integers not greater than the corresponding elements of x. Trunc takes a single numeric argument x and returns a numeri. C floor the floor function in c returns the largest possible integer value which is less than or equal to the given argument.

4 549999 round to floor should become 4 54 and 4 541111 round to ceiling should become 4 55 no i think you d have to multiply your doubles by 100 get floor ceiling and divide by 100. Round up value rounds x upward returning the smallest integral value that is not less than x. Round down value rounds x downward returning the largest integral value that is not greater than x. If you use the tgmath h round macro the type of the argument determines which version of the function is selected.
