Basic data types
In the Z1h programming language, data types are used to declare functions and variables.
The emergence of data types is to divide the data into data with different memory sizes required. When programming, you need to apply for large memory when you need to use big data , You can make full use of memory.
Z1h language has the following data types by category:
| Type | Description | Example |
|---|---|---|
| Boolean | Can only be a constant true or false | isZ1hGood = true |
| Number type | Integer int, float64, etc. | age = 1; pi = 3.1415 |
| String type | A sequence of characters connected by a string of fixed-length characters, using utf-8 encoding to identify Unicode Text | name = 'Z1h' |
| derived types | including pointers, arrays, structures, functions, Maps and other types | obj = {name: 'Somebody', hi: e => {print ('Hello' + this.name) }} |
numeric type
integer
| type | description | minimum | maximum |
|---|---|---|---|
| uint8 / byte | unsigned 8-bit integer | 0 | 255 |
| uint16 | Unsigned 16-bit integer | 0 | 65535 |
| uint32 | Unsigned 32-bit integer | 0 | 4294967295 |
| uint64 | Unsigned 64-bit integer | 0 | 18446744073709551615 |
| int8 | Have 8-bit integer | -128 | 127 |
| Int16 | signed 16-bit integer | -3276 | 32767 |
| int32 / rune | Signed 32-bit integer | -2147483648 | 2147483647 |
| int64 | Signed 64-bit integer | -9223372036854775808 | 9223372036854775807 |
Please use the method of math_big standard library for larger numbers
| Type | Description |
|---|---|
| float32 | IEEE-754 32-bit floating-point number |
| float64 | IEEE-754 64-bit floating-point number |
map and array
| type | description | Example |
|---|---|---|
| map | Key-value pair | me = {name: 'zwr'} |
| [] | Array | lang = ['chinese', 'english'] |
In addition there are derived types
| type | description | examples |
|---|---|---|
| [] byte | byte array | bytearray ("nihao") / "nihao" .bytes |
| [ ] rune | runearray | runearray ("nihao") / "nihao" .runes |
| … | Other types of arrays |
Type conversion
directly use type (variable) for conversion
such as
a =" 123 "
print(a + 456) // 123456
print (int (a) + 456) // 579
b = 888
print (b + 111) // 999
print (string (b) + 111) // 888111
