   ### Question
   
   I notice the code here:
   
   ```java
     static class DoubleLiteral extends ComparableLiteral<Double> {
       DoubleLiteral(Double value) {
         super(value);
       }
   
       @Override
       @SuppressWarnings("unchecked")
       public <T> Literal<T> to(Type type) {
         switch (type.typeId()) {
           case FLOAT:
             if ((double) Float.MAX_VALUE < value()) {
               return aboveMax();
             } else if ((double) -Float.MAX_VALUE > value()) {
               // Compare with -Float.MAX_VALUE because it is the most negative 
float value.
               // Float.MIN_VALUE is the smallest non-negative floating point 
value.
               return belowMin();
             }
             return (Literal<T>) new FloatLiteral(value().floatValue());
           case DOUBLE:
             return (Literal<T>) this;
           case DECIMAL:
             int scale = ((Types.DecimalType) type).scale();
             return (Literal<T>)
                 new DecimalLiteral(BigDecimal.valueOf(value()).setScale(scale, 
RoundingMode.HALF_UP));
           default:
             return null;
         }
       }
   ```
   
   Since Float can have INF -INF, it's greater than normalized float value, but 
if double is INF, it cannot above "max of  all floats?"
