Review comment:
@cloud-fan I pushed the code
```
override def doGenCode(ctx: CodegenContext, ev: ExprCode): ExprCode = {
val ce = child.genCode(ctx)
val evaluationCode = dataType match {
case DecimalType.Fixed(p, s) =>
if (_scale >= 0) {
s"""
${ev.value} = ${ce.value}.toPrecision(${ce.value}.precision(),
$s,
Decimal.$modeStr(), true);
${ev.isNull} = ${ev.value} == null;"""
} else {
s"""
${ev.value} = ${ce.value}.toPrecision(${ce.value}.precision(),
$s,
Decimal.$modeStr(), true);
${ev.isNull} = ${ev.value} == null;"""
// s"""
// ${ev.value} = new java.math.BigDecimal(${ce.value}).
// setScale(${_scale}, java.math.BigDecimal.${modeStr});"""
}
```
Could you please check what's wrong with the following code for the else
part, please ? thanks
```
s"""
${ev.value} = new java.math.BigDecimal(${ce.value}).
setScale(${_scale}, java.math.BigDecimal.${modeStr});"""
```
