QString formatDouble(double value, const QgsNumericFormatContext &context) const override
Returns a formatted string representation of a numeric double value.
virtual void setNumberDecimalPlaces(int places)
Sets the maximum number of decimal places to show.
QVariantMap configuration(const QgsReadWriteContext &context) const override
Returns the current configuration of the formatter.
