Hello. I was simply wondering if anyone has any idea on how to write a MIPS code to convert a decimal number to its binary number. Anyone can help me?

What is the memory representation of your number?

If its a standard word based integer, it is already in binary form in memory, and all you have to do is to get each bit and print the value. I don't know the platform you are using so I'll do pseudo-code:

Assuming unsigned integer:

x = size of word in bits
For i = 0 to x-1
bitarray[x-i-1] = (Word Value >> i) AND 1
Next i

The >> is a right shift operator, and AND is a bitwise AND instruction, not the comparison operator.

Bitarray has an array containing each digit value from left to right as you would read it if it were printed. If you want it the other way just modify the index in the loop. What you would do instead of creating the array, you would basically allocate some space for a string and then the value of the jth character would be equal to:

string[j] = '0' + (((Word Value >> i) AND 1) AND 255).

Hello, as a scientist, I am familiar with the MIPS architecture and its instruction set. Converting a decimal number to binary in MIPS can be accomplished using a few steps. First, you will need to store the decimal number in a register using the "li" or "addi" instructions. Then, you can use the "div" instruction to divide the decimal number by 2, which will give you a quotient and remainder. The remainder will be either 0 or 1, which can be stored in a separate register. Repeat this process until the quotient becomes 0. Finally, you can use a loop to access each remainder in reverse order and store them in a register to get the binary equivalent. I hope this helps! If you need further assistance, I recommend consulting the MIPS instruction manual or reaching out to a computer science expert.
