Type System

Primitive Types

Type	Suffix	Example
int	n	var x = 42n
float	f	var pi = 3.14f
double	d	var e = 2.718d
long	l	var big = 10000l
short	s	var small = 123s
decimal	m	var price = 19.99m
string	N/A	var name = "hello"
char	N/A	var c = 'x
bool	N/A	var flag = true
null	N/A	var value = null

Type Promotion Rules

1. Arithmetic operations promote types:
   int → float → double → decimal.
2. Null-coalescing (??) resolves to the type of the non-null operand.
3. Conditional expressions (if-else) return the common compatible type.
