LeoCalculator 3.4 Description

"Calculator for mortage,compound interest,experiment staatistics and more."

Editor: LeoCalculator performs calculation of mathematical expressions that could include not only basic operations but also elementary and basic statistics functions and brackets. Flexible user interface permits typing expressions at keyboard as well usage only mouse intact with Virtual Keyboard at the application window.

Edit box at the top contains a string of mathematical expression to calculate. It can contain:

numbers in with or without decimal point and with or without a power of 10 like: 7, 3.21, 1.2e-2 or 3.E3;
pi in this application is equal to 3.141592653;
basic mathematical operations + , - ,* , / ;
power of grade operation ^ used like 2^3 = 8;
brackets define order of execution of operations;
elementary mathematical functions: sin,cos,tan,asin,acos,atan,ln,log10,exp,pow10,abs,sqrt,int,min,max,sum,!.
random functions: rand, Gauss
basic statistical functions like mean, SIGMA, student, trust.
user defined variables.
Edit box at left contains definitions of variables:
variables can be any combinations of letters and numbers except spaces and reserved words e, E, pi and function names.
value expressions as usual are numbers but in most cases it could be mathematical expressions too. Tip: variable expression that contains other variables should contain more letters than included variables.
To perform calculation press key "Enter" after expression you want to calculate. The result will appear after mark "=".
Functions:

Behavior most of functions are standard and self-explanatory.

It worth to make some clarification about some of them:

pow10(x) is equal to 10^x

int(5.6) will give 5

!(n) - factorial n

rand(x) will give random value in interval from 0 to x

gauss(x) will give random values that will demonstrate normal distribution around 0 with standard deviation x

min(x1,x2,....,xi) returns minimal value among all arguments

max(x1,x2,....,xi) returns maximum value among all arguments... you can free download LeoCalculator 3.4 now.
