 Вещественное число с фиксированной точностью размером 16 байт. Точность (precision) — максимальное общее число хранимых десятичных разрядов, принимает значения от 1 до 35. Масштаб (scale) — максимальное число хранимых десятичных разрядов справа от десятичной запятой, принимает значения от 0 до значения precision. |
