long int lroundl(long double x);
long long int llround(double x);
long long int llroundf(float x);
long long int llroundl(long double x);
DESCRIPTION
These functions round their argument to the nearest inte
ger value, rounding away from zero, regardless of the cur
rent 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
