Web$\begingroup$ If you want to get a decimal representation of a non-integer, you have to acknowledge that numbers after the decimal point are divided by $10$. What I have done is as close as you can get to division-free division, since the only division carried out is division by $10$, corresponding to a shift of the decimal point. diagram ftthWebWrite the LC-3 code to subtract the value in R1 from the value in R0 and place the result in R5. That is, write the assembly code for R5 := R0 - R1. Problem 2 Write the LC-3 assembly code to determine the maximum of two values. The two input values are in R0 and R1, and the code should place the greater of these two numbers into register R5. diagram french drain
