I Have A Question

[ayao]

Hello  I got My Code Working But i do have some mirror error  about the output and also i wanted to know which is the remainder or the quotient is eax or edx this two seems to confused me alot.

this the original OUPUT:

Number 3 & 8 : 0.375 Number 5 & 6 : 0.833

but my OUPUT IS THIS :
Number 3 & 8 : 375  Number 5 &6 : 833 ; how do i show the zero or show 0.375

- Move to the .data section:
    Div0String   db "0."
    DivString db 20 DUP(?)
    Div1String   db "0."
    DivideString db 20 DUP(?)

- change as follows:
        invoke StdOut, addr Message13
     invoke StdOut, addr Div0String
       
        invoke StdOut, addr Message15
     invoke StdOut, addr Div1String
:P

In case that your results are bigger than 1.000, you need to look into lstrcpy and lstrcat
