muah ha ha ha.

Not that you'd understand this, or anything...but here's a program in MIPS assembly to take a keyboard decimal number and turn it into a hexadecimal number. ph33r.

.data
prompt: .asciiz "Give me a number\n"
buffer: .asciiz "0x       "
.globl main
.text

main:
	li $v0,4
	la $a0,prompt
	syscall

	li $v0,5
	syscall

	move $a0,$v0

	la $a1, buffer
	addi $a1,$a1, 10
	li $s1,57
	li $t0,8

hexloop: 
	andi $t1, $a0, 15
	addi $t1, $t1, 0x30
	ble $t1,$s1, here
	addi $t1,$t1,7
	
here:
	sb $t1, 0($a1)
	addi $a1,$a1,-1
	srl $a0,$a0,4
	addi $t0,$t0,-1
	bgtz $t0, hexloop

li $v0,4
la $a0,buffer
syscall

li $v0,10
syscall

Now...to incorporate it into my first programming assignment...
