We present an efficient and reliable method for computing the unit–in–the–last–place (ulp) of a double precision floating–point number, taking advantage of the standard binary representation for floating– point numbers defined by IEEE Std 754–1985. The ulp is necessary to perform software rounding for robust rounded interval arithmetic (RIA) operations.(More)
Ultraviolet C (UVC) is a DNA damage inducer, and 20 J/m(2) of UVC irradiation caused cell growth inhibition and induced cell death after exposure for 24-36 h. The growth of NIH 3T3 cells was significantly suppressed at 24 h after UVC irradiation whereas the proliferation of A431 cells was inhibited until 36 h after UVC irradiation. UVC irradiation increased(More)
