Rounds a floating-point number to an integer value #include <math.h> double round ( double x ); float roundf ( float x ); long double roundl ( long double x ); The round( ) functions round a floating-point number to the nearest integer value, regardless of the current rounding direction setting in the floating-point environment. If the argument is exactly halfway between two integers, round( ) rounds it away from 0. The return value is the rounded integer value. ExampleSee the example for nearbyint( ) in this chapter.
