     2 <p>These panics represent errors raised by member functions of the <a href="../reference-cpp/E32_EKA2/TRealXClass.html#%3a%3aTRealX" title="class TRealX"><code class="ApiItem">TRealX</code></a> class. Typically, they are the result

     3 of illegal maths operations, such as dividing by zero, or operations which result in overflow.</p><p>The thread causing the panic is terminated.</p>

     4 <code>0</code>

     5 <p>This panic is raised by <code>operator/=</code> of a <a href="../reference-cpp/E32_EKA2/TRealXClass.html#%3a%3aTRealX" title="class TRealX"><code class="ApiItem">TRealX</code></a>, when the divisor is zero</p>

     6 <code>1</code>

     7 <p>This panic is raised by <code>operator+=</code>, <code>operator-=</code> and <code>operator*=</code> of a <a href="../reference-cpp/E32_EKA2/TRealXClass.html#%3a%3aTRealX" title="class TRealX"><code class="ApiItem">TRealX</code></a>, when the the

     8 result of the operation is an overflow.</p>

     9 <code>2</code>

    10 <p>This panic is raised by <code>operator+=</code>, <code>operator-=</code> and <code>operator*=</code> of a <a href="../reference-cpp/E32_EKA2/TRealXClass.html#%3a%3aTRealX" title="class TRealX"><code class="ApiItem">TRealX</code></a>, when the the

    11 result of the operation is an underflow.</p>

    12 <code>3</code>

    13 <p>This panic is raised by <code>operator+=</code>, <code>operator-=</code> and <code>operator*=</code> of a <a href="../reference-cpp/E32_EKA2/TRealXClass.html#%3a%3aTRealX" title="class TRealX"><code class="ApiItem">TRealX</code></a>, when the the

    14 operands are invalid.</p><p>For <code>operator+=</code>, the panic is raised if one of these conditions applies:</p>

    15 <p>the target operand is not a number,</p>

    16 <p>the source operand is not a number,</p>

    17 <p>the target and the source operands are infinite and have different signs.</p>

    18 <p> For <code>operator-=</code>, the panic is raised if one of these conditions applies:</p>

    19 <p>the target operand is not a number, </p>

    20 <p>the source operand is not a number,</p>

    21 <p>the target and the source operands are infinite and have different signs</p>

    22 <p>For <code>operator*=</code>, the panic is raised if one of these conditions applies:</p>

    23 <p>the target operand is not a number, </p>

    24 <p>the source operand is not a number, </p>

    25 <p>the target operand is infinite and the source operand is zero </p>

    26 <p>the target operand is zero and the source operand is infinite.</p>

    27 <p>For <code>operator/=</code>, the panic is raised if one of these conditions applies:</p>

    28 <p>the target operand is not a number,</p>

    29 <p>the source operand is not a number,</p>

    30 <p>the target operand and the source operand are both infinite,</p>

    31 <p>the target operand and the source operand are both zero.</p>

    32 <code>4</code>

    33 <p>This panic is raised by a number of operations on <a href="../reference-cpp/E32_EKA2/TReal64Typedef.html#%3a%3aTReal64" title="typedef TReal64"><code class="ApiItem">TReal64</code></a> and <a href="../reference-cpp/E32_EKA2/TReal32Typedef.html#%3a%3aTReal32" title="typedef TReal32"><code class="ApiItem">TReal32</code></a> types when they complete with
