Function Documentation

AB_Value_AddValue()

int AB_Value_AddValue	(	AB_VALUE *	v1,
		const AB_VALUE *	v2
	)

Referenced by AB::Value::toString().

AB_Value_Compare()

int AB_Value_Compare	(	const AB_VALUE *	v1,
		const AB_VALUE *	v2
	)

Referenced by AB::Value::toString().

AB_Value_Denom()

long int AB_Value_Denom

(

const AB_VALUE *

v

)

Returns the denominator of the given rational number.

Referenced by AB::Value::toString().

AB_Value_DivValue()

int AB_Value_DivValue	(	AB_VALUE *	v1,
		const AB_VALUE *	v2
	)

Referenced by AB::Value::toString().

AB_Value_Dump()

void AB_Value_Dump	(	const AB_VALUE *	v,
		FILE *	f,
		unsigned int	indent
	)

AB_Value_dup()

AB_VALUE* AB_Value_dup

(

const AB_VALUE *

ov

)

AB_Value_Equal()

int AB_Value_Equal	(	const AB_VALUE *	v1,
		const AB_VALUE *	v2
	)

Returns non-zero if v1 and v2 are equal, zero if they are non-equal. Although AB_Value_Compare() can be used for the same purpose, this function is much faster.

Referenced by AB::Value::toString().

AB_Value_free()

void AB_Value_free

(

AB_VALUE *

v

)

AB_Value_fromDb()

AB_VALUE* AB_Value_fromDb

(

GWEN_DB_NODE *

db

)

Create a value from the given GWEN_DB.

AB_Value_fromDouble()

AB_VALUE* AB_Value_fromDouble

(

double

i

)

AB_Value_fromInt()

AB_VALUE* AB_Value_fromInt	(	long int	num,
		long int	denom
	)

Returns a newly allocated rational number, initialized to num/denom.

AB_Value_fromString()

AB_VALUE* AB_Value_fromString

(

const char *

s

)

This function reads a AB_VALUE from a string. Strings suitable as arguments are those created by AB_Value_toString or simple floating point string (as in "123.45" or "-123.45").

Referenced by AB::Value::fromString().

AB_Value_GetCurrency()

const char* AB_Value_GetCurrency

(

const AB_VALUE *

v

)

Referenced by AB::Value::toString().

AB_Value_GetNumDenomString()

int AB_Value_GetNumDenomString	(	const AB_VALUE *	v,
		char *	buffer,
		uint32_t	buflen
	)

Write the value (without the currency) in nominator/denominator form into the given buffer if possibly. This form looks like "12345/6789" (nominator/denominator).

AB_Value_GetValueAsDouble()

double AB_Value_GetValueAsDouble

(

const AB_VALUE *

v

)

This function returns the value as a double. You should not feed another AB_VALUE from this double, because the conversion from an AB_VALUE to a double might be lossy!

Referenced by AB::Value::toString().

AB_Value_IsNegative()

int AB_Value_IsNegative

(

const AB_VALUE *

v

)

Referenced by AB::Value::toString().

AB_Value_IsPositive()

int AB_Value_IsPositive

(

const AB_VALUE *

v

)

Referenced by AB::Value::toString().

AB_Value_IsZero()

int AB_Value_IsZero

(

const AB_VALUE *

v

)

Referenced by AB::Value::toString().

AB_Value_List_dup()

AB_VALUE_LIST* AB_Value_List_dup

(

const AB_VALUE_LIST *

vl

)

Creates a deep copy of an AB_VALUE_LIST object

AB_Value_MultValue()

int AB_Value_MultValue	(	AB_VALUE *	v1,
		const AB_VALUE *	v2
	)

Referenced by AB::Value::toString().

AB_Value_Negate()

int AB_Value_Negate

(

AB_VALUE *

v

)

Referenced by AB::Value::toString().

AB_Value_new()

AB_VALUE* AB_Value_new

(

void

)

AB_Value_Num()

long int AB_Value_Num

(

const AB_VALUE *

v

)

Returns the numerator of the given rational number.

Referenced by AB::Value::toString().

AB_Value_SetCurrency()

void AB_Value_SetCurrency	(	AB_VALUE *	v,
		const char *	s
	)

Referenced by AB::Value::setCurrency().

AB_Value_SetValueFromDouble()

void AB_Value_SetValueFromDouble	(	AB_VALUE *	v,
		double	i
	)

You should not use a double retrieved via AB_Value_GetValueAsDouble as an argument to this function, because the conversion from AB_VALUE to double to AB_VALUE might change the real value.

Referenced by AB::Value::toString().

AB_Value_SetZero()

void AB_Value_SetZero

(

AB_VALUE *

v

)

Referenced by AB::Value::toString().

AB_Value_SubValue()

int AB_Value_SubValue	(	AB_VALUE *	v1,
		const AB_VALUE *	v2
	)

Referenced by AB::Value::toString().

AB_Value_toDb()

int AB_Value_toDb	(	const AB_VALUE *	v,
		GWEN_DB_NODE *	db
	)

Write the given value into the given GWEN_DB.

AB_Value_toDbFloat()

int AB_Value_toDbFloat	(	const AB_VALUE *	v,
		GWEN_DB_NODE *	db
	)

Write the given value into the given GWEN_DB (uses float instead of rational).

AB_Value_toHbciString()

void AB_Value_toHbciString	(	const AB_VALUE *	v,
		GWEN_BUFFER *	buf
	)

Write value to HBCI string (e.g. "11,90" is written as "11,9")

AB_Value_toHumanReadableString()

void AB_Value_toHumanReadableString	(	const AB_VALUE *	v,
		GWEN_BUFFER *	buf,
		int	prec
	)

AB_Value_toHumanReadableString2()

void AB_Value_toHumanReadableString2	(	const AB_VALUE *	v,
		GWEN_BUFFER *	buf,
		int	prec,
		int	withCurrency
	)

AB_Value_toString()

void AB_Value_toString	(	const AB_VALUE *	v,
		GWEN_BUFFER *	buf
	)

This function exports the value in a format which can be recognized by the function AB_Value_fromString. You should not make any assumption about the format of the string created here.
