Hi,
Are bitiwse operations possible OriginC?
Should I include a header file for it?
I encountered compilation errors when using & and |.Does OriginC use a different syntax for them?
Thanks

Hi, whenever I use a bit wise operator in Origin C I get a compiler error : incompatible variable type.
The following is a piece of my code

Dataset ds1("MyData_a");
Dataset ds2("MyData_b");
Dataset ds3("MyData_c");
Dataset ds4("MyData_d");
if(ds2 & 1024 == 1024)
{
ds3 = ds1;
}

I get an error at the if statement (Incompatible variable type)
Can any explain the cause of it?
Thanks.

what are you trying to do here?

ds2 is a Dataset, which is a vector, so I don't see how that can work. If you are trying to get the 1st element to test for a bit, then maybe

int nn = ds2[0];
if((nn & 1024) == 1024)
{
ds3 = ds1;
}
