Introduction :
	The Calculator handles most mathematical operators and functions.

Operators:

	+, -, *, /, ^, %


Functions:

	sqrt, sin, cos, tan,cotan, atan, acos, asin, 	acotan, exp, ln, 10log, fac, 	sinh,cosh,tanh,csch,sech,cotanh, abs, ceil, floor, 	sfac, round, fpart

Logical:

	!, ==, !=, ||, &&, >, < , >=, <=, 

constant
	pi=3.14

numbers
	1-2-3-4-5-6-7-8-9(for base 10)
	A-B-C..........-Z(for base greater than 10)
How to write operations
	sin(3+cos30-sec(tan20))(5+6tanpi)=-4.9911106512301
	(10==10)+6=7 becouse (10==10)=1
	(10==9)+6=6 becouse (10==10)=0
Remark for you:
	*you can use this calc to convert quantities like
	 KG to G
	*althow you can convert from any base number 	 system to other base system like
	 A12F(in base 16)=41263(in base 10)
