Its not about the precisions missing. My point is why the same Read.pm is working in one environment and not working in other with the same code, same input file and same libraries? I need to know what settings(excel attributes) are missing in these two environments. We can write some customization to play with precision values, but, if you compare both the hashes, why is one environment referring to raw data and the other is printing out the exact value in xlsx file?
