Issue Details

I need to perform addition on 16-byte (128-bit) data in LabVIEW. However, I cannot find a native LabVIEW data type that supports 16-byte integer values. How can I perform addition on 16-byte data when LabVIEW only supports data types up to U64?

Solution

LabVIEW does not provide a native 16-byte (128-bit) integer data type. The largest built-in unsigned integer data type available is U64, which supports up to 8-byte (64-bit) values.
 
One possible method is to represent the data as a Boolean array and perform the required arithmetic operations using custom logic. The following example demonstrates how to implement these calculations using a Boolean array representation.
