		ta_e_currency_t *	currency
	)

Discount currency.

Parameters

ta_c_rc_invalid_argument	amount is ta_object_invalid.
ta_c_rc_invalid_argument	amount is not of type loyalty_discount.
ta_c_rc_invalid_argument	currency is null-pointer.

ta_loyalty_discount_get_decimal_value()

ta_e_result_code_t ta_loyalty_discount_get_decimal_value	(	ta_object_t	amount,
		double *	value
	)

Discount amount in major units as double precision floating point value.

Note

Double precision floating point values can not provide the same level of numerical accuracy as int64_t. It is recommended to use the integer based methods.

Parameters

[out]	value	Pointer to variable to write value to.

Return values

ta_c_rc_ok	Value written to value.
ta_c_rc_invalid_argument	amount is ta_object_invalid.

Parameters

[in]	amount	Object instance of type loyalty_discount.
[out]	identifier	Pointer to variable to write object instance to. Object instance is of type string and is not retained. Object instance is ta_object_invalid if identifier is not set in loyalty_discount.

Return values

ta_c_rc_ok	Object instance written to identifier.
ta_c_rc_invalid_argument	amount is ta_object_invalid.
ta_c_rc_invalid_argument	amount is not of type loyalty_discount.
