decrement operator

However, increment and decrement operators are not supported.

Similarly, the decrement operator decreases the value of its modifiable arithmetic operand by 1.

The following C code fragment illustrates the difference between the pre and post increment and decrement operators:

Increment and decrement operators are unary operators that add or subtract one from their operand, respectively.

Octave includes the C-like increment and decrement operators and in both their prefix and postfix forms.

In C-like languages, the increment operator is written as and the decrement operator is written as .

Examples of unary operators in mathematics and in programming include the unary minus and plus, the increment and decrement operators in C-style languages (not in logical languages), and the factorial, reciprocal, floor, ceiling, fractional part, sign, absolute value, complex conjugate, and norm functions in mathematics.
