Question

I'm new to MIPS. How to write a program that prompts the user for a temperature in Celsius and then display the result in Fahrenheit.

Have to use ineteger to float conversion.

Answer 1

//initialize the variables

.data
inputcel: .asciiz "Celcius "
outputfahren: .asciiz "Fahrenheit: "
value1: .float 32.0
value2: .float 5.0
value3: .float 9.0

//read input value to v0 register through accumulator

.text
li $v0, 4
la $a0, inputcel
syscall

li $v0, 6
syscall

//move the values for the calculation to registers

l.s $f1, value1
l.s $f2, value2
l.s $f3, value3

//do the calculations

mul.s $f0, $f0, $f3
div.s $f0, $f0, $f2

add $f0, $f0, $f1

//store the output to v0 register using accumulator

li $v0, 4
la $a0, outputfahren
syscall

li $v0, 2
mov.s $f12, $f0
syscall

//print the value of fahrenheit

li $v0, 10
syscall

This code will convert the temperature in celcius to fahrenheit in floating points.
