One simple approach is using recursion to have the stack record converted digits until conversion . i.e. Are you sure you want to create this branch? A:Every computer has distinguishing features that set it distinct from others. I will post some of my results. One of the biggest problems with binary is that the numbers rapidly become very hard to read. Encoding MIPS Instructions Figure A.10.2 explains how a MIPS instruction is encoded in a binary number. If you want to work with other number bases, like base 10, you'd need to do actual division (MIPS divu) or remainder to remove or isolate the lowest base-10 digit. So to convert this number to binary it is necessary to pad it with left zeros, which have no effect on the number. Or for output, repeated division / modulo by 10 to get the base-10 digits, starting with the lowest.
