> Key: SYSTEMML-1624
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1624
> Project: SystemML
> Issue Type: Bug
> Components: Runtime
> Reporter: Nakul Jindal
> Priority: Critical
>
> For the following program:
> {code}
> A = matrix(0, rows=1, cols=1)
> B = matrix(0, rows=1, cols=1)
> C = A^B
> print(toString(C))
> {code}
> the value printed out is 0.0
> The correct result is 1.0.
> Note that the following code however prints the correct value:
> {code}
> D = 0.0 ^ 0.0
> print(D)
> {code}
> Ping [~mboehm7], [~niketanpansare], [~mwdusenb@us.ibm.com]
