int integerValue = 2;
double doubleValue = 3.337;
var operationResult = integerValue * doubleValue; // operationResult is of
// double datatype.
print('$operationResult, type: ' + operationResult.runtimeType.toString()); // prints "6.674, type: double"
print(operationResult.runtimeType); // prints "double"
