An LonrealType.T is a LONGREAL. This interface is intended to be used to instantiate generic interfaces and modules such as Table and List.
INTERFACE LongrealType; IMPORT Word; TYPE T = LONGREAL; CONST Brand = "Longreal"; PROCEDURE Equal(a, b: T): BOOLEAN;
PROCEDURE Hash(a: T): Word.T;
Return a hash value derived from a. The result is undefined if either a or b is an NaN (not a number) value.
PROCEDURE Compare(a, b: T): [-1..1];
Return -1 if a < b", "0" if "a = b", or "+1" if "a > b. The result is undefined if either a or b is an NaN (not a number) value.
END LongrealType.
Return a = b. The result is undefined if either a or b is an NaN (not a number) value.
