kw_get_real()

Retrieves the real (floating-point) value associated with the given path in the JSON dictionary kw. If the key does not exist, the default_value is returned. Supports automatic type conversion for integers, booleans, and strings when KW_WILD_NUMBER is set.

C

Prototype

double kw_get_real(
    hgobj      gobj,
    json_t     *kw,
    const char *path,
    double     default_value,
    kw_flag_t  flag
);

Parameters

Key	Type	Description
gobj	hgobj	Handle to the GObj instance, used for logging errors.
kw	json_t *	JSON dictionary to search for the specified path.
path	const char *	Path to the desired real value within the JSON dictionary.
default_value	double	Value to return if the key does not exist or is of an incompatible type.
flag	kw_flag_t	Flags controlling behavior, such as KW_REQUIRED, KW_CREATE, and KW_WILD_NUMBER.

---

Return Value

Returns the real (floating-point) value found at path. If the key does not exist or is incompatible, default_value is returned.

Notes

If KW_WILD_NUMBER is set, the function attempts to convert integers, booleans, and numeric strings to a real value. If KW_REQUIRED is set and the key is missing, an error is logged.
