# Available Data Types

Odysseus provides a wide range of data types for your processing.

## Numeric Types

### Double

A double-precision 64-bit IEEE 754 floating point.

### Float

A single-precision 32-bit IEEE 754 floating point.

### Byte

An 8-bit signed two's complement integer. Permissible values are -128 to 127 (inclusive).

### Char

A single 16-bit Unicode character. Permissible values are `'\u0000'`

(or 0) to `'\uffff'`

(or 65,535 inclusive).

### Boolean

A `boolean`

with the two possible values: `true`

and `false`

.

## String Types

### String

A sequence of characters. A string can contain up to ~2^{31} Unicode characters.

## Date and Time Types

### Date

### Timestamp

## Complex Types

### Matrix

A nxm matrix consisting of double-precision 64-bit IEEE 754 floating point numbers.

### Vector

A vector consisting of double-precision 64-bit IEEE 754 floating point numbers.

### List

A list of objects.

The type of objects in the list has to be defined in the schema definition [['timestamp.unixtimestamp', 'List(Integer)']] and can be accessed in expressions: 'timestamp.unixtimestamp[0] = 1162304033'
