Retrieve or set the precision of an HDF5 datatype — H5T_precision • rhdf5

Retrieve or set the precision of an HDF5 datatype

Usage

H5Tset_precision(dtype_id, precision)

H5Tget_precision(dtype_id)

Arguments

dtype_id: ID of HDF5 datatype to set precision of.
precision: The number of bytes of precision for the datatype.

Value

H5Tget_precision() returns an integer giving the number of significant bits used by the given datatype.
H5Tset_precision() is call for its side-effect of modifying the precision of a datatype. It will invisibly return TRUE if this is successful and will stop with an error if the operation fails.

Examples

tid <- H5Tcopy("H5T_NATIVE_INT")
H5Tget_precision(tid)
#> [1] 32
H5Tset_precision(tid, 16L)
H5Tget_precision(tid)
#> [1] 16
