    the rintf() does not exists, but rint():

    NAME
         rint(), nearbyint() - round to nearest int function

    SYNOPSIS
         #include <math.h>

         double rint(double x);

         double nearbyint(double x);

    DESCRIPTION
         rint() and nearbyint() return the integer (represented as a double
         precision number) nearest x according to the current rounding
         direction mode. These functions meet the requirement of the IEEE-754
         standard for an operation that rounds to integer in floating-point
         format.

         The two functions are identical except that rint() raises the inexact
         exception, while nearbyint() does not.

         In the default rounding direction (round to nearest), rint(x) is the
         integer nearest x with the additional stipulation that if
         |rint(x)-x|=1/2, then rint(x) is even. (The same statement applies to
         nearbyint(x).)

         If the current rounding direction is toward negative infinity, rint()
         and nearbyint() are identical to floor(). If the current rounding
         direction is toward positive infinity, rint() and nearbyint() are
         identical to ceil().

         The ISO/ANSI C committee has approved the rint() and nearbyint()
         functions for inclusion in the C9X draft standard.

         To use these functions, compile either with the default -Ae option or
         with the -Aa and -D_HPUX_SOURCE options. Make sure your program
         includes <math.h>. Link in the math library by specifying -lm on the
         compiler or linker command line.

    RETURN VALUE
         If x is +-INFINITY, the rint() and nearbyint() functions return
         +-INFINITY respectively.

         If x is NaN, the rint() and nearbyint() functions return NaN.

    ERRORS
         No errors are defined.
