-------------------------------
Description:
{code:java}
//代码占位符
/** Implementation of {@code MIN} function to calculate the minimum of
* {@code float} values as a user-defined aggregate.
*/
public static class MinFloat extends NumericComparison<Float> {
public MinFloat() {
super(Float.MAX_VALUE, Math::min);
}
}
/** Implementation of {@code MIN} function to calculate the minimum of
* {@code double} and {@code real} values as a user-defined aggregate.
*/
public static class MinDouble extends NumericComparison<Double> {
public MinDouble() {
super(Double.MAX_VALUE, Math::max);
}
}
{code}
was:
