+// T_R32.CPP - Test routines for TReal32
+// Also note that these tests do not generally include testing of special values.  This is done
+// in T_R96 tests and conversions are tested thoroughly, so explicit tests are unnecessary here.
+// Overview:
+// Test functionality of operations on 32bit real numbers.
+// API Information:
+// TReal32. 
+// Details:
+// - Test the conversion from TReal to TReal32 is as expected.
+// - Check addition, subtraction and multiplication of 32-bit floating point
+// numbers are as expected.
+// - Check division of 32-bit floating-point numbers and verify that it is
+// panicked when divided by zero.
+// - Test arithmetic exceptions are raised for
+// - overflow error during addition, subtraction.
+// - overflow, underflow errors during multiplication.
+// - overflow, underflow, divided by zero errors during division.
+// - overflow, underflow, invalid operation errors during conversion
+// from double to float.
+// - Check unary operator, equalities and inequalities operators, pre/post 
+// increment, decrement operators with TReal32 are as expected.
+// Platforms/Drives/Compatibility:
+// All 
+// Assumptions/Requirement/Pre-requisites:
