System.Double.op_Equality Method

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

Syntax

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

Parameters

left
The first value to compare.
right
The second value to compare.

Returns

true if left and right are equal; otherwise, false.

Remarks

The double.op_Equality(double, double) 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 double.Equals(double) 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 double.IsNaN(double) method.
