Lucky Seven Formula Issue

Good luck figuring out the gibberish:

Code:

v113 = v262 == 4001344 || v262 == 14001004;
            v263 = CalcDamage__CalcDamageByWT(v252, a3, v246, v242);
            if ( v113 )
            {
              HIDWORD(Src) = _ZtlSecureFuse((const __int32 *const )(a3 + 72), *(_DWORD *)(a3 + 80));
              a12 = _ZtlSecureFuse((const __int32 *const )(a3 + 72), *(_DWORD *)(a3 + 80));
              v116 = (double)a12 * 1.4;
              v117 = v264 % 7;
              *(double *)v260 = v116;
              Src = (double)SHIDWORD(Src);
              ++v264;
              v115 = v244[v117];
              if ( v116 > Src )
              {
                zswap(v260, (int)&Src);
                v116 = *(double *)v260;
                goto LABEL_177;
              }
              if ( v116 != Src )
              {
                HIDWORD(v118) = 0;
                LODWORD(v118) = v115 % (unsigned int)((char *)&loc_98967F + 1);
                v116 = v116 + (Src - v116) * (double)v118 * 0.000000100000010000001;
              }
              v119 = v116 * 5.5;
              v263 = v119 * (double)v246 * 0.01;
              if ( v252 == 37 || v252 == 38 )
                v263 = v263 * 0.2;
              v124 = a15;
