How to stop getting zeros returned in python? -


this question has answer here:

hi there trying values simple fractions 1/225 or 35/75 keeps returning zeros? appreciated!

mymatrix=[[0,1,1],[1,0,1],[1,1,0]] uu=len(mymatrix) initials_ss=[[150],[300],[100]]    #your initial population size suceptibles initials_zz=[[5],[15],[555]]    #your initial population size zombies initials_rr=[[0],[0],[0]]   #your initial population size removed s_n=np.matrix(initials_ss)   #initial value suceptibles vector z_n=np.matrix(initials_zz)   #initial value zombie vector r_n=np.matrix(initials_rr)   #initial value removed vector  z_nn=np.array(initials_zz) ss=np.sum(s_n,axis=0) zz=np.sum(z_n,axis=0) rr=np.sum(r_n,axis=0)  n=ss+zz+rr nn=1/n[0] tt=np.zeros((uu,uu),int) np.fill_diagonal(tt,nn) print(tt) print(nn) u=np.diag(z_n[:,0]) t=nn*(u*s_n) print(t)

so when try find nn matrix filled zeros on diagonals should have values of fractions?

use type casting. in python have type cast explicitly. following job.

in [92]: float(1)/float(225) out[92]: 0.0044444444444444444   in [95]: float(1)/225 out[95]: 0.0044444444444444444  in [96]: 1/float(225) out[96]: 0.0044444444444444444
