adding operator

An operator that performs arithmetic addition and subtraction operations on groups and numbers.

In AHDL, supported adding operators in Boolean expressions consist of the prefix and binary plus (+) and minus (-) symbols. Supported adding operators in arithmetic expressions consist of the prefix and binary plus (+) and minus (-) symbols. Unary plus and minus symbols are used as prefixes to indicate positive and negative values. Binary plus and minus symbols are used between groups and numbers to indicate addition and subtraction.

In VHDL, supported adding operators consist of the prefix and binary plus (+) and minus (-) symbols and the concatenation operator (&). The concatenation operator (&) is predefined for any one-dimensional array type. See "Section 7.2.4: Adding Operators" in the IEEE Std 1076-1993 IEEE Standard VHDL Language Reference Manual for more information.

In Verilog HDL, supported adding operators consist of the unary and binary plus (+) and minus (-) symbols. See "Section 4.1.5: Arithmetic Operators" in the IEEE Std 1364-1995 IEEE Standard Hardware Description Language Based on the Verilog Hardware Description Language manual for more information.
