augmented assignment

Most binary operators have an associated augmented assignment operator that modifies the given object using the corresponding binary operator. Essentially, x OP= y is equivalent to x = x OP y.

i1 : x = 2

o1 = 2

i2 : x += 3

o2 = 5

i3 : x -= 4

o3 = 1

i4 : x *= 5

o4 = 5

i5 : x /= 6

     5
o5 = -
     6

o5 : QQ

The following augmented assignment operators are supported.

i6 : importFrom(Core, "augmentedAssignmentOperators");

i7 : augmentedAssignmentOperators

o7 = (<<=, >>=, ||=, <==>=, |-=, ??=, ==>=, ===>=, |=, ^^=, &=, ..=, ..<=,
     ------------------------------------------------------------------------
     -=, +=, ++=, **=, *=, \\=, /=, \=, %=, //=, @=, @@=, ^=, _=, ^**=)

o7 : Sequence
