RINT(3) BSD Library Functions Manual RINT(3)NAMErint, lrint, llrint -- round to integral valueSYNOPSIS#include <math.h> double rint(double x); float rintf(float x); long int lrint(double x); long int lrintf(float x); long long int llrint(double x); long long int llrintf(float x);DESCRIPTIONThe rint() and rintf() functions return the integral value nearest to x (according to the prevailing rounding mode) in floating-point format. The lrint() , lrintf() , llrint() and llrintf() functions return the integral value nearest to x (according to the prevailing rounding mode) in the return formats specified. If the rounded value is outside the range of the return type, the numeric result is unspecified and the "invalid" floating-point exception is raised. A range error may occur if the magnitude of x is too large.SPECIAL VALUESrint(+-0) returns +-0 for all rounding modes. rint(+-infinity) returns +-infinity for all rounding modes. All these functions raise the "inexact" floating-point exception if the result differs in value from the argument (except when they raise some other floating-point exception, such as "invalid").SEE ALSOabs(3), fabs(3), ceil(3), floor(3), ieee(3), math(3)STANDARDSThe rint() , rintf() , lrint() , lrintf() , llrint() , and llrintf() functions conform to ISO/IEC 9899:1999(E).BSDJanuary 23, 2003 BSD
