Data types

HARP defines the following data types. See sections netCDF-3, HDF4, and HDF5 for a detailed description of how these data types are mapped to and from the data types supported by each file format.

HARP data type	C data type	bits	sign	range	description
int8	int8_t	8	signed	[-128, 127]	signed 8-bit integer type (two’s complement representation)
int16	int16_t	16	signed	[-32768, 32767]	signed 16-bit integer type (two’s complement representation)
int32	int32_t	32	signed	[-2147483648, 2147483647]	signed 32-bit integer type (two’s complement representation)
float	float	32	signed	[-3.4E38, 3.4E38]	IEEE754 single-precision binary floating-point format (on supported platforms)
double	double	64	signed	[-1.7E308, 1.7E308]	IEEE754 double-precision binary floating-point format (on supported platforms)
string	char*				null-terminated ASCII string
