;; 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 |
