Arithmetic

Operator	Name	Types
`+`	sum	integers, floats, complex values, strings
`-`	difference	integers, floats, complex values
`*`	product
`/`	quotient
`%`	remainder	integers
`&`	bitwise AND
`\|`	bitwise OR
`^`	bitwise XOR
`&^`	bit clear (AND NOT)
`<<`	left shift	integer << unsigned integer
`>>`	right shift	integer >> unsigned integer

See Arithmetic operators in the Go language specification for complete definitions of the shift, quotient and remainder operators, integer overflow, and floating point behavior.

See Bitwise operators cheat sheet for more about how to manipulate bits with operators and functions in package math/bits (bitcount, rotate, reverse, leading and trailing zeros).

Comparison

Comparison operators compare two operands and yield an untyped boolean value.

Operator	Name	Types
`==`	equal	comparable
`!=`	not equal
`<`	less	integers, floats, strings
`<=`	less or equal
`>`	greater
`>=`	greater or equal

Boolean, integer, floats, complex values and strings are comparable.
Strings are ordered lexically byte-wise.
Two pointers are equal if they point to the same variable or if both are nil.
Two channel values are equal if they were created by the same call to make or if both are nil.
Two interface values are equal if they have identical dynamic types and equal concrete values or if both are nil.
A value x of non-interface type X and a value t of interface type T are equal if t’s dynamic type is identical to X and t’s concrete value is equal to x.
Two struct values are equal if their corresponding non-blank fields are equal.
Two array values are equal if their corresponding elements are equal.

Logical

Logical operators apply to boolean values. The right operand is evaluated conditionally.

Operator	Name	Description
`&&`	conditional AND	`p && q` means "if p then q else false"
`\|\|`	conditional OR	`p \|\| q` means "if p then true else q"
`!`	NOT	`!p` means "not p"

Pointers and channels

Operator	Name	Description
`&`	address of	`&x` generates a pointer to `x`
`*`	pointer indirection	`*x` denotes the variable pointed to by `x`
`<-`	receive	`<-ch` is the value received from channel `ch`
