LeoCalculator

LeoCalculator is an application for performing calculation of mathematical expressions that could include not only basic operations but also functions and brackets.
Edit box "Expression" has to contain a string of mathematical expression that is supposed to be calculated.


LeoCalculator contain:

---

numbers in with or without decimal point and with or without a power of 10 like 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 determining order of operation execution;

major functions: sin ,cos ,tan ,asin ,acos ,atan ,ln ,log10 ,exp ,pow10 ,abs ,sqrt. Arguments of the functions have to be an expression surrounded brackets;

variables determined in the edit box "Definitions";

variables can be any combinations of letters and numbers without spaces and reserved words: e, E, pi, sin, cos, tan, asin, acos, atan, ln, log10, exp, pow10, abs, sqrt (case not sensitive);

value expressions as usual are numbers but in most cases it could be mathematical expressions too. Tip: variable expression that contains other variables should be longer than them.
