I knew that there was something wrong with you, | but I never suspected that it was this serious. | | I hope that it's just a temporary effect of drugs and not permanent. Oh, it's permanent alright. According to Dinky the Deranged, x = (-0^2) => x = -0, because sqrt(x^2) = -x for all x <= 0. Chalk it up as another of his "Immortal Fumbles". Androcles |
