I need to write a MIPS program will let the user to enter strings one per line representing valid decimal integers in the range 0 to 999999999999. I need to use 64 bits for each integer. and use some method to convert ascii to integer. here is an example that apparently does it.. but I don't understand it
addi $t3, $t1, -48 # Convert from ascii to integer mul $t2, $t2, $t4 # Multiply to put integer in # right place
also I am not sure what is meant by using 64 bit integers?
