Previously, * Equals performs IEEE 754 equality check for floating points and byte-to-byte checks for other types, including references. * Ieee754Equals performs IEEE 754 for primitive types * TotalOrderEquals performs total order equals to all types, including floating points. Now it is simplified, * Equals performs total order checks for all types. * Ieee754Equals performs IEEE 754 for primitive types. * (TotalOrderEquals is removed.)
