If I had realized that llrint() llrintf() were missing when I added the documentation, I would have supplied the functions as I did for llround. (I had based my evaluation of whether functions existed or not on math.h, which is obviously the wrong way of checking. I'll have to re-check for missing functions in a more vigorous way.) I have created llrint() and llrintf() from the existing lrint() and lrintf() functions. They have been tested and compared against the RHEL5 library (GLIBCx) and pass almost all test cases. llrint() fails a single test case, but lrint() fails exactly the same single case. It actually appears to be an Intel problem, as the rounding is done by the floating point hardware, not in the s_llrint.c/s_lrint.c source code. Because of these two reasons, I'm submitting it despite the one incorrect case. The specific case that fails is: double arg=1.5-LBDL_EPSILON; lrint( arg) and llrint( arg) return 2, and lrint(-arg) and llrint(-arg) return -2, when rounding is set to FE_NEAREST. The correct answers are 1 and -1. The same value with the other 3 rounding modes works fine. The test case of 1.5+LDBL_EPSILON passes (in all rounding modes). Since my addition messes up Ken's patch, I've adjusted his patch (math.h.patch) and included it, too (skipping the qualifiers for llrint&llrintf).

In addition it guards the rint family because there are implemented on i386 only. Ken
