| <div class="block">Rewrites a decimal expression for a specific set of SqlOperator's. In |
| general, most expressions are rewritten in such a way that SqlOperator's |
| do not have to deal with decimals. Decimals are represented by their |
| unscaled integer representations, similar to |
| <a href="https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/math/BigDecimal.html#unscaledValue()" title="class or interface in java.math" class="external-link"><code>BigDecimal.unscaledValue()</code></a> (i.e. 10^scale). Once decimals are |
| decoded, SqlOperators can then operate on the integer representations. The |
| value can later be recoded as a decimal. |
| |
| <p>For example, suppose one casts 2.0 as a decimal(10,4). The value is |
| decoded (20), multiplied by a scale factor (1000), for a result of |
| (20000) which is encoded as a decimal(10,4), in this case 2.0000 |
| |
| <p>To avoid the lengthy coding of RexNode expressions, this base class |
| provides succinct methods for building expressions used in rewrites.</div> |
