Number System

Junlang does not use Arabic numerals. Instead, it represents all numbers using the count of the character 오 along with a few auxiliary symbols.

Single-Digit Numbers

The number of 오 characters represents the digit.

Junlang	Value
오	1
오오	2
오오오	3
오오오오	4
오오오오오	5
오오오오오오	6
오오오오오오오	7
오오오오오오오오	8
오오오오오오오오오	9

Digit Limit

If 10 or more 오 characters appear in a row, the following error occurs. See Error Messages for details.

오 10개? 좀 진정해

Numbers 10 and above must use multi-digit notation.

Zero (0)

0 is represented as 오?.

오?

Junlang	Value
오?	0

Negative Numbers

The negative sign is expressed by prefixing the number with ?.

?[number]

Junlang	Value
?오	-1
?오오	-2
?오오오	-3
?오오오오오오오오	-8

INFO

For more details, see Operators - Unary Operators.

Multi-Digit Numbers

Numbers 10 and above are written by separating digit groups with spaces. Each group represents a single digit (0–9), listed in decimal place order from left to right.

For example, breaking down 오오 오? gives 2 0. Since Junlang separates digits with spaces, this becomes 20.

Junlang	Value	Breakdown
오 오?	10	1, 0
오오 오?	20	2, 0
오오오 오?	30	3, 0
오 오? 오?	100	1, 0, 0
오오 오오오	23	2, 3
오오오오오 오오오오오오오	57	5, 7

Negative numbers work the same way — just prefix with ?.

Junlang	Value
?오 오?	-10
?오오오 오?	-30

Decimals

The integer part and the decimal part are separated by ㅋ.

[integer part]ㅋ[decimal part]

Junlang	Value
오ㅋ오오오오오	1.5
오?ㅋ오오	0.2
오오오 오?ㅋ오오오	30.3
?오오오 오?ㅋ오오오	-30.3
오오오 오ㅋ오오 오오오오오 오오오오오오	31.256

The decimal part uses the same space-separated digit groups as the integer part. In the last example above, 31.256 breaks down as follows:

• Integer part: 오오오 오 → 3, 1 → 31
• Decimal point: ㅋ → .
• Decimal part: 오오 오오오오오 오오오오오오 → 2, 5, 6 → 256

 Note

 ㅋ is also used in Junlang to terminate statements. See Statements and Blocks for details.

Summary

Symbol	Role
오	Represents 1; the count determines the single digit value
오?	0
?	Negative sign (at the very front of the number)
ㅋ	Separates integer and decimal parts
(space)	Separates digit groups
