Atomically increments or decrements the current value. The operation is read-modify-write operation.
1) Performs atomic pre-increment. Equivalent to fetch_add(1)+1.
2) Performs atomic post-increment. Equivalent to fetch_add(1).
3) Performs atomic pre-decrement. Equivalent to fetch_sub(1)-1
4) Performs atomic post-decrement. Equivalent to fetch_sub(1).
For signed Integral types, arithmetic is defined to use two’s complement representation. There
are no undefined results. For T* types, the result may be an undefined address, but the operations otherwise have no undefined behavior.

[edit] Parameters
(none)
[edit] Return value
1,3) The value of the atomic variable after the modification. Formally, the result of incrementing/decrementing the value immediately preceding the effects of this function in the modification order of 
*this.2,4) The value of the atomic variable before the modification. Formally, the value immediately preceding the effects of this function in the modification order of 
*this.[edit] Exceptions
noexcept specification:  
noexcept
  [edit] Notes
Unlike most pre-increment and pre-decrement operators, the pre-increment and pre-decrement operators for atomic types do not return a reference to the modified object. They return a copy of the stored value instead.
