4.2 Language Types Corresponding to netCDF external data types

The following table gives the netCDF external data types and the corresponding type constants for defining variables in the C interface:

Type C #define Bits


byte NC_BYTE 8


char NC_CHAR 8


short NC_SHORT 16


int NC_INT 32


float NC_FLOAT 32


double NC_DOUBLE 64

The first column gives the netCDF external data type, which is the same as the CDL data type. The next column gives the corresponding C preprocessor macro for use in netCDF functions (the preprocessor macros are defined in the netCDF C header-file netcdf.h). The last column gives the number of bits used in the external representation of values of the corresponding type.

Note that there are no netCDF types corresponding to 64-bit integers or to characters wider than 8 bits in the current version of the netCDF library.
