    NAME

    
    
    nearbyint
    
     
    nearbyintf
    
     
    rint
    
     
    rintf
    
     - round to integral value in floating-point format
    
     
    

    LIBRARY

    Lb libm
    
     
    

    SYNOPSIS

       #include <math.h>
    double nearbyint (double x);
    float nearbyintf (float x);
    double rint (double x);
    float rintf (float x);
     

    DESCRIPTION

    The rint ();
    and the rintf ();
    functions return the integral value nearest to Fa x according to the prevailing rounding mode. These functions raise an inexact exception when the original argument is not an exact integer.

    The nearbyint ();
    and nearbyintf ();
    functions perform the same operation, except that they do not raise an inexact exception.
