Literals

The set of literals in Dahlia largely overlaps with those in C with some conveniences.

Numerical constants

Simple unsigned numbers can be defined using:

• Decimal notation: 10, 20, 0
• Octal notation: 070, 010
• Hexadecimal notation: 0x16, 0xdfa

Signed numbers are written with the unary operator -.

Floating point constants

Floating point numbers are defined using C syntax:

1.0
0.123

Booleans

Unlike C, Dahlia treats booleans differently from numbers.

true
false

Most C/C++ backends will simply compile these down to 1 and 0 respectively.
