llround, llroundf, llroundl - round up to next integer value (long long int)

Syntax

#include <math.h> long long int llround(double x); long long int llroundf (float x); long long int llroundl (long double x);

Description  The functions return the integer value (displayed as a number of type long long int)

	nearest to x. The returned value does not depend on the rounding mode currently set. If the difference between x and the rounded result is exactly 0.5, the next highest integer is returned.
Return val.	Integer	value (type long long int) nearest to x if successful.
	Undefined	for overflow or underflow. errno is set to ERANGE to indicate an error.
Errors	llround(), llroundf(), llroundl() fails if: ERANGE      The value is too large, and errno is set to indicate an error.
Errors	abs(), ceil(), floor(), llrint(), lrint(), lround(), rint(), round()
