public class FloatDeserializer extends com.fasterxml.jackson.databind.deser.std.StdDeserializer<Float>
A custom deserializer for Float values, extending StdDeserializer. This deserializer handles special cases for floating-point values represented as strings in JSON, converting them into their corresponding Float constants.

Special handling is provided for:

      public Float deserialize(com.fasterxml.jackson.core.JsonParser p, com.fasterxml.jackson.databind.DeserializationContext ctxt) throws IOException
      Deserializes a JSON string into a Float object.

      Converts special floating-point string representations into their corresponding Float constants. For other valid numeric strings, it parses the value into a Float.

      Specified by:
      deserialize in class com.fasterxml.jackson.databind.JsonDeserializer<Float>
      Parameters:
      p - the JsonParser providing access to the JSON content.
      ctxt - the DeserializationContext for contextual information.
      Returns:
      the deserialized Float value.
      Throws:
      IOException - if an I/O error occurs or the input string is invalid.
