;; Calculator for MenuetOS
;; (c)Ville Turjanmaa
;; Compile with FASM for Menuet
;;
;; «ìªã«ïâ®à 1.1 alpha
;; (c)Pavel Rymovski aka Heavyiron
;;What's new:1)changed design
;; 2)new procedure of draw window (10 decimal digits, 23 binary, "+" not displayed now)
;; 3)window with skin
;; 4)I had used macroses
;; Calc 1.2 alpha
;; 1)added some useful functions, such as arcsin, arccos, arctg, 1/x, x^2
;; Calc 1.3
;; 1)optimised program
