The Vera arithmetic operators (+ - * / % and unary -) perform the respective operations on the two's complement representation of their operands. Operands must be of integral type, and the integer X value is interpreted as 32'bx. The result is of type integer if all operands are of type integer or enum, and is of type bit vector if any operand is a reg or bit vector. If any operand contains an unknown (x) or high impedence (z) values, the result becomes unknown (x). The unary arithmetic operator (-) takes precedence over the binary arithmetic operators. |
