/**
*
*@@ llroundf4 - rounds four floats in to four nearest 64bit integer.
*
*@brief
* boundary test for llroundf4. 0.5 will be rounded to far from 0.
*
*@pre
*
*@criteria
* Run this program and check no error will be occurred.
*
*@note
* when comparing with return of ppu scalar math library
* answer of 0x??7fffff and 0x??ffffff was something strange
*
