;; Calculator for MenuetOS (c) Ville Turjanmaa
;;
;; Compile with FASM
;;
;; Pavel Rymovski (Heavyiron) - version for KolibriOS
;;
;; 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
;; 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
;; Calc 1.33
;; 1) align button captions in proper way, finally!
