64 bits variable mapped in LabView

[Oriana]

Hello,

Does anybody creates a 64 bits variable in LabView?
If you have an ideea, please share it 🙂

Thank you in advance.

It depends what you want to do. If it is just about handling integer values greater than 2^32 then the simplest method really is to use a double precision floating point value. That one can represent integers up to about 2^56 without loss of precision.

If it is about interfacing to external software such as shared libraries you will have to create a cluster with two int32 values in there and pass this to the Call Library Node. This however won't help with arithmetic operations inside LabVIEW unless you write your own Add, Subtract, Multiply etc, VIs to handle that datatype.

Yes, the same ideea with the cluster I have also but is not working ...


Thank you for your help ... I'll try again ...
