+// T_REALX.CPP - Test routines for TRealX
+// Overview:
+// Test the functionality of a class that encapsulates 64 bit extended precision
+// real values.
+// API Information:
+// TRealX
+// Details:
+// - Test the constructor and assignment operator with signed, unsigned, 64 bit
+// integer, float and double values.
+// - Check the conversion of TRealX value to signed, unsigned, 64 bit integer,
+// float and double values is as expected.
+// - Set TRealX variable with some special values and check it is as expected.
+// - Test addition, multiplication, division of TRealX values is as expected.
+// - Test Unary operators, comparison of two TRealX values are as expected.
+// Platforms/Drives/Compatibility:
+// All
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
