A numeric formatter which returns a simple text representation of a value.
QString id() const override
Returns a unique id for this numeric format.
QString visibleName() const override
Returns the translated, user-visible name for this format.
int sortKey() override
Returns a sorting key value, where formats with a lower sort key will be shown earlier in lists.
QgsNumericFormat * clone() const override
Clones the format, returning a new object.
QString formatDouble(double value, const QgsNumericFormatContext &context) const override
Returns a formatted string representation of a numeric double value.
