This calculator allows you to record any math expression in same way as you think about it. As example, you can write expression like this:
((6.5*5+7*1.5)*53)*30

And you will get result in the next line.
= 68370

Than you can easily modify input or even copy it to new line and get updated result. You can send calculation sheet by mail, clean it or open new one. Comments for result and for calculation lines are available, so you won't forget what you calculated and why.

Supported features:

1. Comments for calculations.
2. Radian/degrees selection.
3. 39 predefined math functions (just select any of them from list).
4. Calculation can be send by mail.
5. Delete/copy/paste whole line without selection.

Following math functions are supported:
RND () random number [0, 1]
RND(x) random integer number [0, x]
ROOT(x, y) x^ (1/y)
FRAC(x) fraction part
INT(x) integer part
CEIL(x) smallest integral value that exceeds x
FLOOR(x) largest integral value less than x
ROUND(x, d) rounds x to d decimal digits, round(x) = round(x, 0)
%( percentage operator) (5% =>0.05)
^ (exponent operator) (2^3 =>8)
SIN(x) sine = sin(x)
COS(x) cosine = coos(x)
TAN(x) tangent = tan(x)
ASIN(x)arc sin = sin inverse

TANH(x)Hyperbolic tan
ABS(x)absolute(x)
LOG(x)log-10(x)
LN(x)ln(x) = log-e (x)
SQRT(x)square root = x^(1/2)
POW(x,y)power(number, exponent)
FACT(x)factorial(x) = x!
PIPi constant
EXP(x)exponential = e^x
Ee = Euler constant
SQR(x)square = x^2
CUBE(x)cube = x^3
CURT(x)cubic root = x^(1/3)
INV(x)1/x
NEG(x)negative = -x
PCT(x)percentage = x/100
Mean(A,B,C,..) = Arithmetic Average
DEVI(A,B,C) = Standard Deviation
