Unary operators are operators that take exactly one argument.

Unary Arithmetic Operator

Operator 

-

 can be used as a prefix unary operator to change sign of a signed value. Unary prefix operator 

+

 can be 

used also, but it doesn’t affect data.

For example:

b = -a

Unary Bitwise Operator

The result of the 

not

 (bitwise negation) operator is the bitwise complement of the operand. In the binary representation 

of the result, every bit has the opposite value of the same bit in the binary representation of the operand.

not

bitwise complement (unary); inverts each bit

Example: 

not 0x1234              ‘ equals 0xEDCB

Address and Indirection Operator

In the mikroBasic PRO for dsPIC, address of an object in memory can be obtained by means of an unary operator 

@

. 

To reach the pointed object, we use an indirection operator 

^

 on a pointer. See Pointers section for more details.

^

accesses a value indirectly, through a pointer; result is the value at the address to 

which operand points

@

constructs a pointer to its operand

See Pointers for more details on this subject

Note: Besides these, sizeof and explicit conversion unary operators are supported also.
