Operators

Boolean logical operators	Bitwise and shift operators	Arithmetic operators	Equality operators	Comparison operators
No Operator 1 & 2 | 3 ^ 4 && 5 || 6 !	No Operator 1 & 2 | 3 ^ 4 ~ 5 << 6 >> 7 >>>	No Operator 1 + 2 - 3 * 4 / 5 % 6 ++ 7 --	No Operator 1 == 2 !=	No Operator 1 > 2 < 3 >= 4 <=

Variables and Scope

No	Name	Example	Doc	Data Type	.NET type
1	bool	bool isVisible = true;	link	value	System.Boolean
2	byte	System.Int32 a = 123;	link	value	System.Byte
3	sbyte	System.Int32 a = 123;	link	value	System.SByte
4	char	char a = 'A';	link	value	System.Char
5	decimal	double a = 1.1;	link	value	System.Decimal
6	double	double a = 1.1;	link	value	System.Double
7	float	double a = 1.1;	link	value	System.Single
8	int	System.Int32 a = 123;	link	value	System.Int32
9	uint	System.Int32 a = 123;	link	value	System.UInt32
10	nint	System.Int32 a = 123;	link	value	System.IntPtr
11	nuint	System.Int32 a = 123;	link	value	System.UIntPtr
12	long	System.Int32 a = 123;	link	value	System.Int64
13	ulong	System.Int32 a = 123;	link	value	System.UInt64
14	short	System.Int32 a = 123;	link	value	System.Int16
15	ushort	System.Int32 a = 123;	link	value	System.UInt16
16	object	string a = "hello world";	link	reference	System.Object
17	string	string a = "hello world";	link	reference	System.String
18	dynamic	dynamic a = 1;	link	reference	System.Object
