New SMath Studio 0.90 Stable available

Absolutely free mathematical program with "paper"-like interface and numerous computing features (now with integrated mathematical reference book).

Controls:

With consecutive pushing of this button you can choose: "1", delimiter of the number ",", "square root - sqrt", "n-th root - nthroot", "integral - int", "function to find roots of equations - solve". To lock any variant just stop pushing this button 1 second.

With consecutive pushing of this button you can choose: "number related to the button", "symbols related to this button". To lock any variant just stop pushing this button 1 second.

With consecutive pushing of this button you can choose: "plus operator", "minus operator", "multiplication operator", "division operator", "exponentiation operator", "plus/minus operator", "factorial", "vector multiplication operator". Also with this pushed button you can highlight the part of equation by using Left/Right buttons.

By "clicking" on this button program will numerically calculate equation (this means "="); by pushing button more than 0,4 sec. program will symbolically calculate equation (this means "->"). Also, if the cursor located on the right of the not defined variable or not defined function this button will create a definition operator (this means ":=" ).

Removing last character (Backspace). In the mathematical reference book this button means "Back".
