Matthias Boehm created SYSTEMML-1981:
----------------------------------------
Summary: Wrong value type propagation in function w/ auto cast of
inputs
Key: SYSTEMML-1981
URL: https://issues.apache.org/jira/browse/SYSTEMML-1981
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
Priority: Minor
The following code returns the output as {{DOUBLE}} although it's supposed to
return {{INT}}.
{code}
foo = function(Matrix[double] X, int input) return (int out) {
out = input;
for(i in 1:2) {
tmp = sum(X);
out = input + as.integer(tmp);
}
}
X = seq(1,100);
xmax = max(X); #input of type double
y = foo(X, xmax); #auto casting
print(y);
{code}
This is a minor issue but creates warnings that are annoying if such a function
is called very often:
{{code}}
17/11/01 20:49:00 WARN controlprogram.ProgramBlock: Function output out has
wrong value type: DOUBLE.
{{code}}
