 The following table summarizes how Avro types are mapped to corresponding Ballerina types. These rules are applicable when serializing/deserializing Ballerina data according to an Avro schema.

+>**Note:** The Ballerina [`int`](https://ballerina.io/spec/lang/2023R1/#section_5.2.3) type can represent integers up to 64 bits in size using the two's complement representation. Therefore, it can handle both `int` (32-bit signed integer) and `long` (64-bit signed integer) Avro types.
+
+>**Note:** The Ballerina [`float`](https://ballerina.io/spec/lang/2023R1/#section_5.2.4.1) type supports the IEEE 754-2008 64-bit binary (radix 2) floating-point number standard. Therefore, it can handle both `float` (32-bit single precision IEEE 754 floating-point number) and `double` (64-bit double precision IEEE 754 floating-point number) Avro types.
