Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 2025 (64-bit)
10.2.0.188
Operating System:WIN11


HDF import App (HDF Connector 1.22) does not import numbers with full precision. Only 5 digits are imported. Is there a way to obtain full float double precision numbers?

Hi Giselher,

The data is imported with full precision, just that by default it only shows 5 digits in the worksheet. Please refer to this page on how to change the decimal display settings globally or within a specified worksheet column.

Thank you

Hello James,

unfortunately this didn't do the trick. Apparently Origin interpretes my hdf data at some point as string datatype, but the true hdf datatype is Variable-length of 64-bit floating-point. After connecting the hdf file the origin column shows as "text and numeric" but the entry is leftbound and the numbe of digits cannot be changed. When I switch the column to "numeric" it will become rightbound and I can change the number of digits, however it only fills the additional digits with zeros, not the full precision od the original hdf data. The first 8 digits are correct, just the precision is missing Is there a way to fix this?

Best regards,
Giselher
