> The issue can be reproduced using the following DML script:
> {code}
> X = matrix(seq(1, 9), rows=3, cols=3)
> #X[1,2] = X[1,2] / sum(X == 10)
> X[1,2] = 0 / 0
> for(i in 1:nrow(X)) {
>         print(">" + as.scalar(X[i,1]) + " " + as.scalar(X[i,2]) + " " + as.scalar(X[i,3]))
> }
> print(toString(X))
> {code}
> For NaN, it produces following output:
> {code}
> >1.0 NaN 3.0
> >4.0 5.0 6.0
> >7.0 8.0 9.0
> 1.000 � 3.000
> 4.000 5.000 6.000
> 7.000 8.000 9.000
> {code}
> For Infinity, it produces following output:
> {code}
> >1.0 Infinity 3.0
> >4.0 5.0 6.0
> >7.0 8.0 9.0
> 1.000 ∞ 3.000
> 4.000 5.000 6.000
> 7.000 8.000 9.000
> {code}
