These panics represent errors raised by member functions of the TRealX class. Typically, they are the result
+of illegal maths operations, such as dividing by zero, or operations which result in overflow.
The thread causing the panic is terminated.
+0
+This panic is raised by operator/= of a TRealX, when the divisor is zero
1
+This panic is raised by operator+=, operator-= and operator*= of a TRealX, when the the
+result of the operation is an overflow.
2
+This panic is raised by operator+=, operator-= and operator*= of a TRealX, when the the
+result of the operation is an underflow.
3
+This panic is raised by operator+=, operator-= and operator*= of a TRealX, when the the
+operands are invalid.
For operator+=, the panic is raised if one of these conditions applies:
the target operand is not a number,
+the source operand is not a number,
+the target and the source operands are infinite and have different signs.
+ For operator-=, the panic is raised if one of these conditions applies:
the target operand is not a number,
+the source operand is not a number,
+the target and the source operands are infinite and have different signs
+For operator*=, the panic is raised if one of these conditions applies:
the target operand is not a number,
+the source operand is not a number,
+the target operand is infinite and the source operand is zero
+the target operand is zero and the source operand is infinite.
+For operator/=, the panic is raised if one of these conditions applies:
the target operand is not a number,
+the source operand is not a number,
+the target operand and the source operand are both infinite,
+the target operand and the source operand are both zero.
+4
+This panic is raised by a number of operations on TReal64 and TReal32 types when they complete with
+an error code other than: KErrArgument, KErrDivideByZero, KErrOverflow or KErrUnderflow.
