c99 [ flag... ] file... -lm [ library... ] #include <math.h> double nearbyint(double x);
float nearbyintf(float x);
long double nearbyintl(long double x);
These functions round their argument to an integer value in floating-point format, using the current rounding direction and without raising the inexact floating-point exception.
Upon successful completion, these functions return the rounded integer value.
If x is NaN, a NaN is returned.
If x is ±0, ±0 is returned.
If x is ±Inf, x is returned.
