             Summary: Inconsistent printing in toString method for Infinity and 
NaN
                 Key: SYSTEMML-1373
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1373
             Project: SystemML
          Issue Type: Bug
          Components: Runtime
            Reporter: Niketan Pansare
            Assignee: Nakul Jindal
            Priority: Minor


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}
