Double::Equality Operator

.NET Framework 4.6 and 4.5

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

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

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.

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.
