6.3 NetCDF-3 Classic and 64-Bit Offset Data Types
NetCDF-3 classic and 64-bit offset files support 6 atomic data types,
and none of the user defined datatype introduced in NetCDF-4.
The following table gives the netCDF-3 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
pre-processor macro for use in netCDF functions (the pre-processor
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.
