Re: [Hdf-forum] Minus zero in Dataset

[Eduardo Jauch]

Hello Matthieu, The problem is that if I set the values of an array to 0.0, how is it possible that it to be interpreted as -0.0? And unfortunatelly, it seems it matter. The code that uses this data works if compiled to 64 bits, but fails if compiled to 32 bits... Cheers, Eduardo. TECNICO Lisboa - MARETEC Secção de Ambiente e Energia Av.

Your actual data has both, that's all. It doesn't matter. Cheers, Matthieu 2014-02-21 12:22 GMT+00:00 Eduardo Jauch <eduardo.ja...@ist.utl.pt>: Hello :) I'm generating some HDF files and in many datasets, when I open with HDFView, some of the values are set to -0.0, but they should be 0.0. Anyone found this already? Some hint on what can be? Best regards, Eduardo Jauch -- TECNICO Lisboa - MARETEC Secção de Ambiente e Energia Av.
