NAME

       round_jiffies_up - function to round jiffies up to a full second

SYNOPSIS

       unsigned long round_jiffies_up(unsigned long j);

ARGUMENTS

       j
	   the time in (absolute) jiffies that should be rounded

DESCRIPTION

       This is the same as round_jiffies except that it will never round down. This is useful for timeouts for which the exact time of firing does
       not matter too much, as long as they don't fire too early.

NAME

       lrint, lrintf, lrintl, llrint, llrintf, llrintl - round to nearest integer

SYNOPSIS

       #include <math.h>

       long int lrint(double x);
       long int lrintf(float x);
       long int lrintl(long double x);

       long long int llrint(double x);
       long long int llrintf(float x);
       long long int llrintl(long double x);

DESCRIPTION

       These  functions  round	their argument to the nearest integer value, using the current rounding direction.  If x is infinite or NaN, or if
       the rounded value is outside the range of the return type, the numeric result is unspecified.  A domain error may occur if the magnitude of
       x is too large.

RETURN VALUE

       The rounded integer value.

ERRORS

       EDOM   The magnitude of x is too large and (math_errhandling & MATH_ERRNO) is non-zero.

CONFORMING TO

       C99.
