Table 2. Unary Operators

Operator Description

- Two’s-complement arithmetic negation

~ One’s-complement bitwise negation

Binary operators are symbols that appear between two expressions and perform

an operation to combine the values of the two expressions. Table 3 lists the

binary operators.

* Multiplication

/ Division with integral truncation

& Bitwise AND

^ Bitwise Exclusive OR

The special operators are symbols that instruct the Neuron Assembler to perform

a specific action. The values of expressions that use special operators are

computed at link time. Table 4 lists the special operators.

Table 4. Special Operators

Operator Description

@ Specifies a special operator function

* Specifies the absolute address of the

current assembly instruction (only

computable at link time for relocatable

segments)

A special operator function begins with the @ character, followed by the function

name, and then by a parenthesized expression. The function names can be

specified in either lower or upper case. Table 5 lists the special operator

functions.
