/**
 * <B>Title:</B> Division Query Operator <br>
 * <B>Keywords:</B> query <br>
 * <B>Assertion ID:</B> A14.6.2-31. <br>
 * <B>Assertion Description: </B> The division 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><code>float, double, Float, Double</code>
 *   <LI><code>BigDecimal, BigInteger</code>
 * </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.
