Primitive Data Types

The Rux compiler recognize such primitive data types.

Signed integer types

Type	Size	Minimum Value	Maximum Value
int8	1 byte	−27 = −128	27−1 = 127
int16	2 bytes	−215 = −32,768	215−1 = 32,767
int32	4 bytes	−231 = −2,147,483,648	231−1 = 2,147,483,647
int64	8 bytes	−263 ≈ −9.223372 × 1018	263−1 ≈ 9.223372 × 1018
int128	16 bytes	−2127 ≈ −1.7014118 × 1038	2127−1 ≈ 1.7014118 × 1038
int256	32 bytes	−2255 ≈ −5.7896045 × 1076	2255−1 ≈ 5.7896045 × 1076
int512	64 bytes	−2511 ≈ −6.2771017 × 10153	2511−1 ≈ 6.2771017 × 10153

Unsigned integer types

Type	Size	Minimum Value	Maximum Value
uint8	1 byte	0	28−1 = 255
uint16	2 bytes	0	216−1 = 65,535
uint32	4 bytes	0	232−1 = 4,294,967,295
uint64	8 bytes	0	264−1 ≈ 1.8446744 × 1019
uint128	16 bytes	0	2128−1 ≈ 3.4028237 × 1038
uint256	32 bytes	0	2256−1 ≈ 1.1579209 × 1077
uint512	64 bytes	0	2512−1 ≈ 1.3407808 × 10154

Floating-point types

Type	Size	Approximate Range	Significant Digits
float8	1 byte	±1.0 × 10-2 to ±2.5 × 101	~1 digit
float16	2 bytes	±6.1 × 10-5 to ±6.5 × 104	~3 digits
float32	4 bytes	±1.2 × 10-38 to ±3.4 × 1038	~7 digits
float64	8 bytes	±2.2 × 10-308 to ±1.8 × 10308	~15–16 digits
float128	16 bytes	±3.4 × 10-617 to ±1.2 × 10617	~34 digits
float256	32 bytes	±1.0 × 10-1985 to ±1.0 × 101985	~72 digits
float512	64 bytes	±1.0 × 10-5950 to ±1.0 × 105950	~154 digits

Boolean types

Type	Size	Range
bool8	1 byte	false or true
bool16	2 bytes	false or true
bool32	4 bytes	false or true
bool64	8 bytes	false or true
bool128	16 bytes	false or true
bool256	32 bytes	false or true
bool512	64 bytes	false or true

false is equal to 0, true is equal to 1

Character types
