Numeric

There are 4 numeric types in NC: byte, int, uint, and float.

Integer

byte

Bytes are represented by the byte type. This is an 8-bit unsigned integer and is usually used to write to and read from files or other streams of data where the data may not necessarily be UTF-8 text. An example of this is reading and parsing binary formats like images or fonts.

byte b = 97
byte b = 0x61
byte b = 0o141
byte b = 0b01100001

int

The int type is a 64-bit signed integer type.

You can declare ints by simply writing a number without a decimal point.

int my_num = 1

uint

The uint type is a 64-bit unsigned integer. A uint can be declared similarly to an int:

uint my_num = 1 // cannot be negative
uint my_num = 1u // can also use the `u` suffix

Binary, Hexadecimal and Octal

Binary numbers need to be prefixed with 0b, for example, 0b1011.

Hexadecimal numbers need to be prefixed with 0x, for example, 0xFF. The part after the 0x is case-insensitive.

Octal numbers need to be prefixed with 0o, for example, 0o777.

float

The float type is a 64-bit floating point number, following the IEEE 754 standard. It can be declared by writing a number with a decimal point.

float my_float = 1.0
