The Double value type represents a double-precision 64-bit number with values ranging from negative 1.79769313486232e308 to positive 1.79769313486232e308, as well as positive or negative zero, PositiveInfinity, NegativeInfinity, and Not-a-Number ( NaN ).

Double complies with the IEEE 754 standard for binary floating-point arithmetic.

Double provides methods to compare instances of this type, convert the value of an instance to its String representation, and convert the String representation of a number to an instance of this type.

For information about how format specification codes control the String representation of value types, see Formatting Base Types.

This type implements interfaces IComparable, IFormattable, and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.
