Hi, I got a strange error message: *** Break *** floating point exception The following is part of my code which looks perfect to me. ---------------------------------------------------------------- ... // ********************************************************************* // 3. BGO fit // ********************************************************************* // calculate each layer incident position Float_t ebgo[10][40]; // values for ebgo[10][40] are assigned ... Float_t bsum[10]={0., 0., 0., 0., 0., 0., 0., 0., 0., 0.}; Float_t bmax; Float_t ebxs = 0.; Int_t jbmax, i, j; for (i=0; i<1; i++) { // Find max crystal at each layer bmax = ebgo[i][0]; jbmax = 0; for (j=1; j<40; j++) { bsum[i] += ebgo[i][j]; if (ebgo[i][j] > bmax) { bmax = ebgo[i][j]; jbmax = j; } } printf("bmax[%d][%d]=%g\n",i+1,jbmax+1,bmax); // Calculate incident position at each layer for (j=0; j<40; j++) if (ebgo[i][j] > 0.1*bmax) ebxs += ebgo[i][j] * bgox[j]; } -------------------------------------------------------------- When I execute the macro, it prints out "bmax[1][10]=0.13472". Then it gives me err message: *** Break *** floating point exception It means up to "print" statement it works. Is there something wrong with my code after "print" statement? My version is root_v0.9.OSF1.V3.2.tar. Is it due to old version ? --- Thanks in advance! Jayoung
