<short>Determines whether the specified arguments have the same value.</short>
<descr>
<p>
<var>SameValue</var> is a <var>Boolean</var> function used to compare the values in <var>AValue1</var> and <var>AValue2</var> to determine if they have the same value. SameValue calls the overloaded SameValue routine in the <file>math.pp</file> unit to get the return value for the method. The return value is <b>True</b> when both AValue1 and AValue2 have the same value.
<var>SameValue</var> is a <var>Boolean</var> function used to compare the values in <var>AValue1</var> and <var>AValue2</var> to determine if they have the same value. The return value is <b>True</b> when both AValue1 and AValue2 have the same value. It is defined as an abstract virtual method in <var>TSpinEditExBase</var>, and must be implemented in descendent classes to compare the data type for the specialization.
</p>
<p>
This method was introduced to ensure that the type specialization for the class instance is used when value comparisons are performed. Specifically, it allows the 64-bit compiler on Windows to determine which of the overloads in Math.SameValue is called for the <var>Currency</var> type.
SameValue is used in the implementation of storage specifiers for the <var>Increment</var>, <var>MinValue</var>, and <var>MaxValue</var> properties.
