Go language data types
In the Go programming language, data type used to declare functions and variables.
Data types appear to divide the data into different memory size required for data programming time required by large data when it needs to apply for a large memory, you can take advantage of memory.
Go Language There are several types of data by category:
| No. | Type and Description |
|---|---|
| 1 | Boolean <br> Boolean values can only be a constant true or false.A simple example: var b bool = true. |
| 2 | <br>Numeric type integer int and float float, Go language support for integer and floating point numbers, and native support for complex numbers, which bit operations using complement. |
| 3 | String type: The character string is a string of fixed length connecting sequence of characters. Go strings are connected by a single byte. Go byte string of language use UTF-8 Unicode text encoding logo. |
| 4 | Derived type: include:
|
Digital Type
Go is also based on the type of architecture, such as: int, uint and uintptr.
| No. | Type and Description |
|---|---|
| 1 | uint8 Unsigned 8-bit integer (0-255) |
| 2 | uint16 16-bit unsigned integer (0-65535) |
| 3 | uint32 32-bit unsigned integer (0-4294967295) |
| 4 | uint64 64-bit unsigned integer (0-18446744073709551615) |
| 5 | int8 Signed 8-bit integer (-128 to 127) |
| 6 | int16 16-bit signed integer (-32768 to 32767) |
| 7 | int32 Signed 32-bit integer (-2147483648 to 2147483647) |
| 8 | int64 Signed 64-bit integer (-9223372036854775808 to 9223372036854775807) |
Float:
| No. | Type and Description |
|---|---|
| 1 | float32 IEEE-754 32-bit floating point type number |
| 2 | float64 IEEE-754 64-bit floating point type number |
| 3 | complex64 32-bit real and imaginary |
| 4 | complex128 64-bit real and imaginary |
Other types of digital
Here are more other numeric types:
| No. | Type and Description |
|---|---|
| 1 | byte Similar uint8 |
| 2 | rune Similar int32 |
| 3 | uint 32 or 64 |
| 4 | int And the same size as uint |
| 5 | uintptr Unsigned int, used to store a pointer |
