| PositiveInfinity |
Represents positive infinity. This field is constant. |
Methods
| Name | Description |
|---|---|
| CompareTo(Double) |
Compares this instance to a specified double-precision floating-point number and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the specified double-precision floating-point number. |
| CompareTo(Object) |
Compares this instance to a specified object and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the specified object. |
| Equals(Double) |
Returns a value indicating whether this instance and a specified Double object represent the same value. |
| Equals(Object) |
Returns a value indicating whether this instance is equal to a specified object. |
| GetHashCode() |
Returns the hash code for this instance. |
| GetTypeCode() | |
| IsFinite(Double) |
Determines whether the specified value is finite (zero, subnormal, or normal). |
| IsInfinity(Double) |
Returns a value indicating whether the specified number evaluates to negative or positive infinity. |
| IsNaN(Double) |
Returns a value that indicates whether the specified value is not a number (NaN). |
| IsNegative(Double) |
Determines whether the specified value is negative. |
| IsNegativeInfinity(Double) |
Returns a value indicating whether the specified number evaluates to negative infinity. |
| IsNormal(Double) |
Determines whether the specified value is normal. |
| IsPositiveInfinity(Double) |
Returns a value indicating whether the specified number evaluates to positive infinity. |
| IsSubnormal(Double) |
Determines whether the specified value is subnormal. |
| Parse(ReadOnlySpan<Char>, NumberStyles, IFormatProvider) |
Converts a character span that contains the string representation of a number in a specified style and culture-specific format to its double-precision floating-point number equivalent. |
| Parse(String, IFormatProvider) |
Converts the string representation of a number in a specified culture-specific format to its double-precision floating-point number equivalent. |
| Parse(String, NumberStyles, IFormatProvider) |
Converts the string representation of a number in a specified style and culture-specific format to its double-precision floating-point number equivalent. |
| Parse(String, NumberStyles) |
Converts the string representation of a number in a specified style to its double-precision floating-point number equivalent. |
| Parse(String) |
Converts the string representation of a number to its double-precision floating-point number equivalent. |
| ToString() |
Converts the numeric value of this instance to its equivalent string representation. |
| ToString(IFormatProvider) |
Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information. |
| ToString(String, IFormatProvider) |
Converts the numeric value of this instance to its equivalent string representation using the specified format and culture-specific format information. |
| ToString(String) |
Converts the numeric value of this instance to its equivalent string representation, using the specified format. |
| TryFormat(Span<Char>, Int32, ReadOnlySpan<Char>, IFormatProvider) |
Tries to format the value of the current double instance into the provided span of characters. |
| TryParse(ReadOnlySpan<Char>, Double) |
Converts the span representation of a number in a specified style and culture-specific format to its double-precision floating-point number equivalent. A return value indicates whether the conversion succeeded or failed. |
| TryParse(ReadOnlySpan<Char>, NumberStyles, IFormatProvider, Double) |
Converts a character span containing the string representation of a number in a specified style and culture-specific format to its double-precision floating-point number equivalent. A return value indicates whether the conversion succeeded or failed. |
| TryParse(String, Double) |
Converts the string representation of a number to its double-precision floating-point number equivalent. A return value indicates whether the conversion succeeded or failed. |
| TryParse(String, NumberStyles, IFormatProvider, Double) |
Converts the string representation of a number in a specified style and culture-specific format to its double-precision floating-point number equivalent. A return value indicates whether the conversion succeeded or failed. |
Operators
| Name | Description |
|---|---|

Thread Safety
All members of this type are thread safe. Members that appear to modify instance state actually return a new instance initialized with the new value. As with any other type, reading and writing to a shared variable that contains an instance of this type must be protected by a lock to guarantee thread safety.
