WebWhen computer programs store numbers in variables, the computer needs to find a way to represent that number in computer memory. Computers use different strategies based on whether a number is an integer or not. Due to limitations in computer memory, programs sometimes encounter issues with roundoff, overflow, or precision of numeric variables. WebNov 24, 2024 · So to represent +32 we need 7 bits. -32 = 1100000 (1st bit 1 - sign bit as negative) So to represent -32 we need 7 bits. But answer is given as 6 bits to store -32 and 7 bits to store +32 (positve case i understood, negative in my opinion it should be 7 bits). His reason - one 1 bit enough to represent negative number. frs school
