;; Calculator for MenuetOS (c) Ville Turjanmaa
;;
;; Compile with FASM for Menuet
;;
;; Pavel Rymovski (Heavyiron) - kolibri version
;; What's new:
;; Calc 1.1
;; 1) changed design
;; 2) new procedure of draw window (10 decimal digits, 23 binary, "+" not displayed now)
;; 3) window with skin
;; 4) used macroses
;; Calc 1.2
;; 1)added some useful functions, such as arcsin, arccos, arctg, 1/x, x^2
;; Calc 1.31
;; 1)optimised program
;; 2)new type of window (you need kernel 114 revision or higher)
;; Calc 1.32
;; 1)fixed arccos
appname equ 'Calc '
version equ '1.32'
