rdm_bcdToStringWithScale()

RDM_RETCODE rdm_bcdToStringWithScale ( const RDM_BCD_T * operand,
uint8_t scale,
RDM_BOOL_T useExponent,
char * result,
size_t inBytes,
size_t * bytesOut
)

#include <rdmbcdapi.h>

Convert a BCD number with scale to a string.

This function converts a BCD number with scale to a string.

The number of bytes needed for the conversion can be retrieved through

bytesOut by setting result to NULL.
Return values
sOKAY Success
Parameters
[in] operand Operand to be converted
[in] scale Scale to use for the output
useExponent [IN] Use exponent in output
[out] result Result of the conversion
[in] inBytes Length of result buffer in bytes
[out] bytesOut A pointer to the number of bytes returned (can be NULL)

rdm_bcdToUInt16()

uint16_t * result
)

#include <rdmbcdapi.h>

Convert a BCD number to an uint16_t.

This function converts a BCD number to an uint16_t.

Return values
sOKAY Success
Parameters
[in] operand Operand to be converted
