WebOr, use SUM with positive and negative numbers. Type a positive value in one cell, and a negative value in another. In a third cell, use the SUM function to add the two cells together. In this example, cell D6 has the budgeted amount, and cell E6 has the actual amount as a negative number. F6 has the formula =SUM(D6,E6). WebFeb 7, 2024 · If the left-hand operand is of type int or long, the right-shift operator performs an arithmetic shift: the value of the most significant bit (the sign bit) of the left-hand operand is propagated to the high-order empty bit positions. That is, the high-order empty bit positions are set to zero if the left-hand operand is non-negative and set to ... lowest price ge 7195sfss

"~((uint16_t) 0) results in negative value, because result of (uint16_t) 0 is promoted to int before bitwise complement is performed. In general you should prefer unsigned integers (wide enough to avoid type promotion) when using bit shifting. My suggestion would be to use unsigned int zero instead: return (~(~0U << shift)); " - Error left shift of negative value
