DESCRIPTION
The round(), roundf(), and roundl() functions return the nearest integral value to x; if x lies halfway between two integral values, then these functions return the integral value with the larger absolute value (i.e., they round away from zero).STANDARDS
These functions conform to ISO/IEC 9899:1999 (“ISO C99”).HISTORY
