WebSep 29, 2024 · double a = 12.3; System.Double b = 12.3; The default value of each floating-point type is zero, 0. Each of the floating-point types has the MinValue and MaxValue constants that provide the minimum and maximum finite value of that type. The float and double types also provide constants that represent not-a-number and infinity values.
