Double::Equality Operator

.NET Framework 4.5

Other Versions

.NET Framework 4

Returns a value that indicates whether two specified Double values are equal.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

public:
static bool operator ==(
	double left, 
	double right
)

Parameters

left: Type: System::Double
The first value to compare.

right: Type: System::Double
The second value to compare.

Return Value

Type: System::Boolean
true if left and right are equal; otherwise, false.

Remarks

The Equality method defines the equality operator for Double values.

If two Double::NaN values are tested for equality by using the equality operator, the result is false; two Double::NaN values are not considered equal. If they are tested for equality by calling the Equals method, the result is true. When you want to determine whether the value of a Double is not a number (NaN), an alternative is to call the IsNaN method.
