Data Type

This document describes the various data types provided by the Wave programming language. The Wave programming language can store and manipulate values using various data types. Major data types include integers, floating-point numbers, and strings. Each data type defines the characteristics and memory handling of the data.

Integer Type​

The integer type is used to store integer values. By default, integers are declared as i32 (signed 32-bit integer) and u32 (unsigned 32-bit integer). The Wave programming language offers options for fine-grain control over the range of integers.

  • i8 ~ i1024: Signed integer type, can be set from 8-bit to 1024-bit.
  • u8 ~ u1024: Unsigned integer type, allows size setting from 8-bit to 1024-bit.

Example:

var a :i32 = 100;
var b :u32 = 200;

Floating-Point Type​

The floating-point type is used to store real-number values. By default, floating-point numbers are declared as f32. Additionally, it offers various size options for precise definition of floating-point numbers.

  • f32 ~ f1024: The floating-point type can be set from 32-bit to 1024-bit. This allows for higher precision in real-number calculations.

Example:

var pi :f32 = 3.14;
var e :f64 = 2.71828;

String Type​

The string type is used to handle text data. Use the str keyword to declare a string. Strings are typically defined inside double quotes ("), allowing assignment to variables.

Example:

var text :str = "Hello Wave";

Boolean Type​

The boolean type represents data with True or False values. Primarily used in conditional statements, with values set to true or false.

Example:

var isActive :bool = true;
var isAvailable :bool = true;

Character Type​

The character type is used to store a single character. Declared using the char keyword, it holds only a single character value.

Example:

var letter :char = 'A';

Byte Type​

The byte type is used to store data of 1-byte size. It is mainly useful for handling binary data. Declared using the byte keyword.

Example:

var byteData :byte = 0xFF;

Pointer Type​

The pointer type is used to reference memory addresses. Declared using the ptr keyword, it's used to store memory addresses.

Example:

var ptr :ptr<T> = &someVariable;

Array Type​

The array type is used to sequentially store multiple identical data types. Using the array keyword, you can specify the size or type of the array.

Example:

var numbers: array<i32, 5> = [1, 2, 3, 4, 5];

Since each data type can be set with various ranges and sizes, users can select a type that suits their needs for efficient memory management and computation.
