I have the following program, which has the formula of: (b + c*b - a/4)/(a*b -1)
However, when I run it it gives me different results that it should be what might be the cause, can you help me to provide me updated version, will really appreciate it.
The program:
.486
.model flat, stdcall
option casemap: none
include \masm32\include\windows.inc ; For a management by the modes of Window
include \masm32\include\user32.inc ; For using MessageBox

include \masm32\include\masm32.inc ; For using FloatToStr
includelib \masm32\lib\user32.lib ; For using MessageBox
includelib \masm32\lib\kernel32.lib ; For using ExitProcess
include Ext_macros.inc
NUM macro Q, M, N
MOV AL, M ; Copy number B to register AL
CBW ; Extension AL to AX
MOV BL,4 ; Copy constant "4" to register BL
IDIV BL ; Division register AX, as variable "B" on constant "4", quotient in AL
ADD AL, N ; Addition register AL and "C", as "C+B/4"
SUB AL,33 ; Subtraction from register AL constant "33", as "C+B/4-33"
CBW ; Extension AL to AX
MOV Q, AX ; Copy value of numerator from registry AX to registry BX
endm
DEN macro R, X, Y, Z
MOV AL, X ; Copy number A to register AL
MOV CL, Z ; Copy number C to register CL
IMUL CL ; Multiplication register AL and "A" on registry CL (variable C), result in AX
MOV CH, Y ; Copy number B to register CH
IDIV CH ; Division register AX, as result "A*C" on variable "B", quotient in AL
MOV DL,1 ; Copy constant "1" to register DL
SUB AL, DL ; Subtraction from register AL constant "1", as "A*C/B-1"
MOV R, AL ; Copy value of denominator from registry AL to registry R
endm
