WebSep 14, 2024 · The processor flags are single bits and you don't perform arithmetic on them; asking whether the flags are signed or unsigned is meaningless. Cases (b) and (c) are if the text is talking about a specific programming language. This would almost certainly have to be C, based on the syntax and talking about comparisons returning integers.

WebApr 4, 2024 · In a mathematical operation in C++ (e.g. arithmetic or comparison), if one signed and one unsigned integer are used, the signed integer will be converted to unsigned. And because unsigned integers can not store negative numbers, this can result in loss of data. Consider the following program demonstrating this: Webnumeric_std is a library package defined for VHDL.It provides arithmetic functions for vectors. Overrides of std_logic_vector are defined for signed and unsigned arithmetic. It defines numeric types and arithmetic functions for use with synthesis tools.

WebSigned and unsigned division are different operations, owing to the need to round towards zero. For example, in unsigned 4-bit integer arithmetic, 1001/0010 yields 0100 (9/2 = 4), while in signed 4-bit integer arithmetic it yields 1101 (–7/2 = –3).
