/**
 *<B>Title:</B> Sign Inversion Query Operator
 *<BR>
 *<B>Keywords:</B> query
 *<BR>
 *<B>Assertion ID:</B> A14.6.2-29.
 *<BR>
 *<B>Assertion Description: </B>
The numeric sign inversion operator (<code>-</code>) is supported for all types
as they are defined in the Java language. This includes the following types:
<UL>
<LI><code>byte, short, int, long, char, Byte, Short Integer, Long, Character</code></LI>
<LI><code>float, double, Float, Double</code></LI>
<LI><code>BigDecimal, BigInteger</code></LI></UL>
The operation on object-valued fields of wrapper types (<code>Boolean, Byte,
Short, Integer, Long, Float</code>, and <code>Double</code>), and numeric types
(<code>BigDecimal</code> and <code>BigInteger</code>)
use the wrapped values as operands.
