Data Types

Brunost is dynamically typed. Types are checked at runtime, not at compile time.

Integer

64-bit signed integers.

låst a er 42
låst b er -7
låst c er a + b   // 35

Arithmetic operators: +, -, *, / (truncating integer division).

Float

64-bit floating-point numbers.

låst pi er 3.14159
låst half er 1.0 / 2.0   // 0.5

Mixed integer/float arithmetic coerces the integer to float:

låst result er 5 + 2.5   // 7.5

String

UTF-8 text, delimited by double quotes.

låst greeting er "God dag"
låst combined er "Hello, " + "world!"

Concatenation with + coerces non-strings:

terminal.skriv("Svaret er: " + 42)   // "Svaret er: 42"

Escape sequences

Sequence	Meaning
\n	Newline
\t	Tab
\r	Carriage return
\\	Backslash
\"	Double quote

terminal.skriv("linje1\nlinje2")   // prints on two lines
terminal.skriv("sitat: \"hei\"")   // sitat: "hei"

String operations are available in the streng module.

Boolean

låst yes er sant
låst no er usant

Logical operators:

Operator	Meaning	Notes
og	AND	Short-circuits on usant
eller	OR	Short-circuits on sant
ikkje	NOT	Prefix

Truthiness rules:

Value	Truthy?
sant	yes
usant	no
0	no
0.0	no
"" (empty string)	no
[] (empty list)	no
{} (empty map)	no
Everything else	yes

Null — inkje

Functions that perform I/O (like terminal.skriv) return inkje. You generally don't need to store it.

låst result er terminal.skriv("hello")
// result is inkje

List

An ordered, heterogeneous, dynamic sequence.

låst numbers er [1, 2, 3, 4, 5]
låst mixed er [1, "two", 3.0, sant]
låst empty er []

Use [] to access elements by index (0-based):

låst first er numbers[0]    // 1
låst third er numbers[2]    // 3

Additional list operations are available in the liste module.

Hashmap

String-keyed dictionary.

låst person er {"name": "Kari", "age": 30}
låst empty er {}

Access values with [] subscript syntax or the kart module:

låst name er person["name"]    // "Kari"
låst age er person["age"]      // 30

Type coercion summary

Operation	Result type
int + int	integer
int + float	float
string + any	string
int / int	integer (truncated)
