Assignment Operators

= Assignment Any Any A = 1

B = C = A

+= Addition

assignment

Integer-integer Integer x = 1

x += 1 = 2

String-string String a = "one "

a += "two" = "one two"

Raw byte-raw byte Raw z = '001122'

z += '334455' = '001122334455'

List-list List x = [1, 2]

x += [3, 4] = [1, 2, 3, 4]

Integer-list List y = 1

y += [2, 3] = [1, 2, 3]

Integer-string String a = "number = "

a += 2 = "number = 2"

*Note: integer-string concatenation uses decimal

conversion.

String-list List s = "one"

s + ["two"] = ["one", "two"]

-= Subtraction

assignment

Integer-integer Integer y = 3

y –= 1 = 2

*= Multiplication

assignment

Integer-integer Integer x = 3

x *= 1 = 3

/= Division

assignment

Integer-integer Integer s = 3

s /= 1 = 3

%= Modulus

assignment

Integer-integer Integer y = 3

y %= 1 = 0

>>= Right shift

assignment

Integer-integer Integer b = 0b11111110

b >>= 1 = 0b01111111

<<= Left shift

assignment

Integer-integer Integer a = 0b11111110

a <<= 3 = 0b11111110000

&= Bitwise AND

assignment

Integer-integer Integer a = 0b11111110

a &= 0b01010101 = 0b01010100

^= Bitwise exclusive

OR assignment

Integer-integer Integer e = 0b11111110

e ^= 0b01010101 = 0b10101011

|= Bitwise inclusive

OR assignment

Integer-integer Integer i = 0b11111110

i |= 0b01010101 = 0b11111111
